Alright, I was burning my tires on my GST and obviously I messed something up in my tranny. The car still drives but unless I am accelerating it makes the clicking sound. I can wiggle the half shaft and the intermediate shaft around a little. I had the car in nutral and was turning the tire in the video and the clicking sound is comming from the area of the tranny between where the 2 shafts connect to it.
I am guessing I have to pull my transmission since I broke something, do I have to pull the passenger side half shaft buy unbolting the tie rod and pulling the hub out a little bit and then unbolting the intermediat shaft and then I will have enough room to pull it?
I have a 91 gst with equal length half shafts.

Could be an input shaft bearing.

It still drives but should I be concerned about driving it, not that I plan on it? I'm guessing I need to pull it to find out right? There might have been a quieter noise that I noticed before for a while and then I think today did it in.

i dont think its your trans. my guess is you broke your cv axle.

 

[bertrenolds]

Definitely not the half shafts, It's inside the the transmission that the noise is comming from. I thought I broke a half shaft as well but they are both solid and like I said the noise is comming from inside the transmission. When I turn the passenger side wheel the intermiediate shaft for the drives side doesn't spin at all, it moves just a little but then you hear the clicking noise.

 

[dsm92talonboost]

so you think its inside the transmission? well in your transmission the only bearing we got is, your throw out bearing,input shaft bearing, and your main seals that hold input shaft in and the countershaft/mainshaft. than you got your gears/dogteeth, shift forks synchro's and your idler gear.

and your synchro sleeves.

 

[bertrenolds]

Are all of those right in the area between where the 2 shafts get put into the transmission? I am going to have to find a broken down picture of this transmission to see what is right there.

 

[dsm92talonboost]

transmissions are made up of four thinngs, counter shaft,input shaft,idler gears, bearings.

I pulled my tranny out and I'm going to open the case tomorrow. I was looking at vfaqs and I am wondering if the bearings on the front differential are the same for both sides?

Yes, the bearings are the same for both sides of the front differential. You likely toasted your differential or had a bearing failure on the front diff.

dsm92talonboost - please do not post any more transmission knowledge as you clearly do not understand the intricate details of these transmissions with your generalizations.

The F5M33 transmission is composed of an input shaft with 3rd/4th/5th floating gears and 1st/2nd/reverse drive gears, the intermediate shaft with 1st/2nd floating gears and 3rd/4th (main drive gear is 4th) and 5th drive gears, an output shaft that drives the front differential through power transfer from the intermediate shaft 4th gear, the reverse idler gear that is driven off the 1st/2nd hub and slider with the reverse synchro being utilized through the reverse idler gear lever actuating the 5th/reverse shift rail to engage reverse, and the front differential itself.

This does not sound like an input shaft bearing failure; it is more likely a failed front differential, or a damaged intermediate shaft or failed output shaft bearing. Personally, I put my money on front differential cross-shaft/spider gear damage based simply on a sound without even watching the video.

If you would like a tutorial of how to disassemble your F5M33, here is a link to an old thread for someone with a broken shift fork, but it will get you to the same place in the transmission to pull the front diff and output shaft out to inspect the carnage.

Good luck,

Just pulled it open last night and the differential is fine, my 4th,5th, and intermediate shaft are toast. My tranny is now a huge paperweight! I am currently trying to purchase another tranny locally. Hopefully I don't destroy the next one with wheel hop since there was alot of chipping on my gears it was more then likely the reason for the failure.
