crazy sound

[gst25401]

Ok, this is the problem. Whenever I come off of the clutch and start to give the car throttle
i get a grinding noise from the front passenger side. what could this be?

This could be a little extreme, but I had a similiar problem along with some vibrations. It ended up being a bad axle joint. I would check all the suspension on that side.

 

[taino787]

do you still get the noise if you turn off the car and push it?
if yes does it stop when the car stops rolling?

 

[gst25401]

The whole problem started when I had my clutch, clutch master cyl., and slave cyl replaced. (all oem mits parts)

 

[taino787]

any updates. i beleive i have the same problem?

What is yours doing? Another thing, will a turbo still build boost if it is no good?

I'm not to knowleagable and internals but it sounds like the clutch wasn't installed properly. Expecially if you didn't experience this until after the install. The front passenger side is where the clutch/transmission is located.

Another thing, will a turbo still build boost if it is no good?

A turbo will spool as it is going bad but when it finally blows up you will not be able to boost at all and may notice a large amount of smoke from tailpipe. Listen for a grinding noise as it is spooling to check if it is going bad. This will be one of the compressor wheel hitting the housing. Also take off the intake snorkel and move the compressor wheel side to side and in and out. If you have a lot of play then it is going bad.

The damn thing engages and disengages right from the floor.

You asked for help and ideas, and that is all he gave you was a suggestion. Is the clutch properly adjusted? Can you hold the clutch in with the car in gear and rev the car witout it going anywhere? how many miles on the new clutch so far?

There could be a number of things it could be and the little bit of information you've provided isn't going to be enough to help you diagnose the problem. You'll need to spend more time checking things. Here's a few suggestions.

Slowly accelerate in a safe area like a side road, back of a shopping center or unpopular street. Pay attention to the noise and see if it changes frequency with vehicle speed. See if the noise changes at all with speed and take note of the differences.

Next is do the same thing and once you have it at about 15-25 mphs shut off the engine and see if you can still here the noise. Next, do the same thing with the vehicle in neutral. Note any noise you hear and how it changes as the vehicle slows down.

Next would be to jack up the front of the vehicle (FWD only, AWD do NOT try this). Support the vehicle with Jack stands. Set the parking brake. Pull the front wheels and inspect the brakes. Reinstall the wheels. Spin the wheels by hand and see if the noise can be heard. This may require spinning slowly or as fast as you can by hand. Next, have a helper crank the engine and put it in gear. Lay under the car and see if you can isolate the noise.

It is VERY important that you have high quality jack stands and the parking brake set. It is also VERY important that the driver KNOW not to accelerate quickly, suddenly or allow the engine/transmission to shake violently as this may cause the vehicle to rock off of the jack stands.

Use of a screw driver may be necessary to isolate the noise. Put the pointed end on several NON-MOVING parts such as the transmission tail section, main section, differential section OF the transmission and on brake caliper brackets as well as the steering knuckle. Hold the plastic section against your ear. EXTREME CAUTION must be used when doing this to make sure the screwdriver does not contact anything moving or you may die from being impaled through your skull. Sounds scary but it's done properly on a daily basis by professionals and shadetrees alike. But I'm sure there's a few people that have been seriously injured when doing this improperly.

Your options for failing parts include:
Brakes metal to metal
Bad Wheel Bearing
Bad CV Joints
Failed differential bearings inside the transmission
Pitted gears in 1st, 2nd, the differential Ring Gear or other gears inside the Transmission
There have also been 4g63 transmissions to have a bearing wear through the side cover closest to the wheel.
Improperly installed clutch
Damage to Transmission case during repairs.

You'll have to do more leg work unless you want to start doing expensive guess work.
