2G AWD Front Wheel Bearing Questions - Parts Interchangeability with 3G and Evo ?'s

[twicks69]

Hey Guys,

Just looking to see if anyone can confirm parts interchangeability between the front wheel bearings for 2G AWD DSM's vs. 3G Eclipse and Evo 8/9's.

2G AWD DSM's:
The front wheel bearing part number for 94-1999.03.3 is MR455004.
The front wheel bearing part number for 1999.04.1 - 1999.04.3 is MR334386.

3G Eclipse
The front wheel bearing part number for 99-2005 is MR334386.

Evo 8/9:
The front wheel bearing part number for 2002-2007 is MB914617.


With that said......

Can anyone confirm that the Evo 8 hub assembly (wheel bearing/hub and studs) bolts up to a 2G AWD front spindle, and has the SAME dimensions as the 2G AWD and 3G Eclipse?

The Evo 8 wheel bearing is the cheapest of the three, hence why I have questions!


Thanks guys!

Here is some info on the rear hubs: http://www.dsmtuners.com/forums/han...buy-rear-awd-wheel-bearings-hub-assembly.html

Yeah I saw that thread, but no pertinant information regarding the front hubs.

My rear hubs are using a larger diameter axle than stock (DSS stage 5 axles and hubs), and my front bearings are going to get redone while the rears get taken care of.

Thanks for the link,

Tim

Evo hubs will not work on a 2G. Bolt pattern/axle spline diameter are different.

3G hubs work on 99 Eclipses only - rotor centering dims are different. Change to 99+ rotors and they work.

There are cheap aftermarket front hubs available from SKF and Timken if you don't mind non-OEM sized studs. NAPA hubs are OEM-priced, but either SKF or TImken sourced - they have the same small spline studs. Timken/SKF seem the most cost effective, so long as you don't have several hundred dollars invested in ARP wheel studs...The SKF/Timken hubs appear to last about as long as OEM - 1 season safely - so a switch to appropriately sized ARP studs is the logical course.

Great info, as always, Charles.
What would one have to do to run "normal" studs? Besides buy them. Would they just drop into the Timken units? Would using their small splined studs make cause for new lug nuts?
I guess what I'm after is, to what detriment would running the Timken style studs be?

 

[twicks69]

Charles, thanks for the heads-up! This really helped!

I just picked up TWO for $87.65 SHIPPED!

I am assuming you were using REPM283701. If so, do you know the ARP wheel stud applicable for this model that is 53mm of threads, 63mm of body and 67mm with flange? These are the dimensions of my rear studs from DSS. I am using 48mm open-ended lug nuts.

Thank you so much!

 

[ACM]

I don't remember which ARP studs fit the SKF/NAPA/Timken hubs, but all three have a spline diameter of 0.5", so look through the ARP studs for a .5" base diameter and you should be all set. IIRC there are several different ones - different lengths and whether or not there's an unthreaded lead-in (which I prefer). The studs have the same DSM thread size, just the smaller spline diameter.

Charles

 

[twicks69]

Charles, THANKS! I found the same ones as the rear -- 100-7708 -- 0.509" Knurl diameter, 2.500" complete length, 0.315" knurl length, M12x1.5mm pitch.

$29.00 later, I have two sets of the studs shiped via Jegs!

 

[twicks69]

*****UPDATE*****

The wheel bearings arrived and are very nice pieces. Unfortunately, the dimensions given above for the wheel studs were wrong. The actual measured knurl diameter for wheel studs is 0.565" -- ARP 100-7717 is the proper part number for this application utilizing a longer 3.0" stud.

Unfortunately, these studs are substantially more expensive than the parts I originally ordered.

Lesson learned from this??? Measure the studs for your application prior to ordering them blindly. It cost me an additional $29.00 for hardware that now sits on my shelf. Yay.

Either way, hopefully someone else learns from this.

BTW, the wheel bearings were purchased from Race Parts - Auto Parts - Car Parts - The Internet Racepages - RacePages.Com -- part number REPM283701
As well, you can use the coupon code "rpcart" for an additional 10% off your order.

 

[ACM]

Interesting - then the hubs you received are neither NAPA, SKF or Timken - you have found a fourth source....565" is the stock spline diameter -which means you saved me from buying several new sets of ARP studs - thank you ! If I switch to these hubs I can reuse my DSM/Evo ARP wheel studs, I don't have to buy 3 sets of new ARP studs...

It is interesting that RacePages does not list a brand for those hubs, but they do list brands for rear hubs - are there any identification marks on the packaging ? This is actually a great find - just not for you - because this is the only non-OEM hub we've come across that uses OEM dimensioned studs. There has to be a reason Mitsu spec'd that larger spline diameter - it wasn't just so they could waste extra money...

Actually, I think they do list the brand - it appears to be "Replacement". Also worthy of note is the site lists two rear Timken hubs - one appears to be a wheel hub - TM512181, it is shown with the wheel flange and everything, whereas Timken shows just the hub bearing, and it's only $100 !! If that pans out, it's a gem of a discovery for AWD owners ! Probably has the wrong studs, but hey

Hopefully they will last as long as the other brands, which based on Scott's and my experience is about 1.5 seasons...

 

[twicks69]

Yeah, the stock stud that came in the "replacement" brand bearing assembly has a knurl diameter of 0.565", a total length of 1.70" from flange to tip, and a threaded length of 1.0460" from chamfer to tip. Knurl length is 0.2635".

The wheel bearing flange thickness is 0.4545" with a flange ID of 2.85" before the chamfer, and a inner flange OD of 2.6230" that extends outward 0.6045" from the flange.

The inner flange is a perfect fit, and the overall quality looks pretty decent.

As for packaging, it came in a white no-label box that had the part number "Replacement - REPM283701" labeled on it.


I have confirmed that the original 1999 AWD front wheel bearing from my car is exactly the same dimensionally as well as the OEM 1999 AWD wheel studs for every dimension listed above.

These are a direct replacement bolt-in part for the 2G FWD and AWD front wheel bearing assemblies.

Also worthy of note is the site lists two rear Timken hubs - one appears to be a wheel hub - TM512181, it is shown with the wheel flange and everything, whereas Timken shows just the hub bearing, and it's only $100 !!

That rear TM512181 is actually just the wheel bearing section of the hub assembly. Here's a better photo: TIMKEN 512181 Wheel Bearing Module

Hmm - I wonder how beefy a press would be required for that ? JNZ only wants $150 for a rear hub - price is dropping, works for me...

Oh wow - JNZ has OEM front hubs for under $100 !! Why even bother rolling dice for aftermarket hubs at this price ?

 

[Strm Trpr]

Mentor Mitsu has them for $94.54.
http://www.trademotion.com/partlocator/index.cfm?siteid=213934
It's located under:
-Front Suspension
-Brake Components
-Hub Assy

Only items that come up are: Hub assy Back - 2wd 95-99 $118.75, or
Front hub and bearing, eclipse - 1995-99 - Awd $94.54

 

[Scott McIntyre]

Hmm - I wonder how beefy a press would be required for that ?

For me, it's not really an option as I want to replace the whole assembly (not just the bearing) to reduce potential failure points.

Oh wow - JNZ has OEM front hubs for under $100 !! Why even bother rolling dice for aftermarket hubs at this price ?

What part number are you using? When I look it up, I get the following:

MR455004 $122.71
MR334386 $181.99
​

 

[snowborder714]

I wonder if he's looking up MR103664 (resolves to R455004 for some reason on JNZ's site) which was superseded by MR455004. They show up as under $98 on JNZ.

You can get MR455004 for $114 from mitsparts.com.

 

[ACM]

I didn't use part numbers, I just looked up parts for a '97 Eclipse AWD.

Maybe they're listing the wrong parts ?

 

[Scott McIntyre]

Ah yes, it reads...

Front hub and bearing, eclipse - 1995-99 - 1995-99 95-99 $97.69

No part number. Strange.

 

[snowborder714]

Price matches the part number I posted. I'd be interested to know what they have to say about that item.

 

[ACM]

I get uncomfortable when I see "99 Eclipse" included - Some time in the '99 build series the cars got 3G hubs and rotors which have a different rotor centering setup than 95-98. If the actual part # crosses to the 3G then you can't use it without the matching rotor. As far as I know, I was once sent that hub as being the supercession for the 95 part, and of course the rotor is the last thing you put on when reassembling...

The 3 & 4G share front hubs iirc, so it would make sense that part is cheaper as it's still current.

 

[DSSA]

Figured I would give a break down from ASA on this, these are all the new part numbers.
2G AWD & FWD Front
MR455004 1st week January 94-3rd week March 99.
MR334386 1st week April of 99-3rd week April 99.
2G AWD Rear
MR403968 (same as EVO 8/9)
2G FWD Rear
MB892408 (same as 3G)
EVO 8/9 Front
MB914617
EVO 8/9 Rear
MR403968
3G Eclipse Front
MR334386
3G Eclipse Rear
MB892408

Originally some of these parts had different numbers for ABS and non-ABS cars, they have all since been merged to one part number.
Now CAPS/ASA is known to have errors

Bollox !

REPM283701 fits 9904+ 2G/3G rotors ONLY - it does NOT fit pre-9904 rotors 8-(

I just pulled my new hubs out of their box and immediately saw the "double ring" machining around the rotor locating centre boss. Pulled some rotors and sure enough they all stop 2-3mm before landing flush on the hub face.

This is not too terrible if you need (OEM-spec) rotors as well as you can just order 3G rotors and be all set. However, if you have a set of TCE or AEM rotors you're SOL.

RaceParts were very accommodating, but if you need to retain 9404-9903 rotors, it means going with Timken, SKF, or no-name NAPA hubs and dealing with the weirdo wheel studs. Or going stock - hopefully they're still $95 each, and not back up to $190...

Rats...

 

[Strm Trpr]

However, if you have a set of TCE or AEM rotors you're SOL.

I came across this with my TCE kit.
I had to replace my driver's front hub with a Napa hub that is stepped.
I sent the aluminum rotor hat back to Todd @ TCE and he opened the center bore to 3g specs.

Eventually I'll have to pull my passenger front hub to replace it and will need to send out the rotor hat for center bore enlargement as well.

Todd was very accommodating and turn around time was 5 working days total from the day I shipped the hat to him.

Sorry to bring this one back, but would these ones be the hubs I need for my 97:
Mitsubishi Parts | OEM Mitsubishi Parts | Genuine Mitsubishi Parts

Looks right to me. I'd imagine these are true OEM so I wouldn't have to worry about the different sized studs that have been mentioned on the cheaper replacement versions?
