Question worn-out gears?

what the symptoms of worn-out gears? there's a big clunk sound that comes from under my car and i just cant figure out what it is! it happens when i crusing @ 30-40 mph, at that speed when i push on the throttle and let go it clunks 2 times, when it starts to accelerate and when it starts decelerating.

i been under the car many times and i check for loose parts but nothing, mounts r ok, drive shaft, ect...

I'm curious about this as well, it doesn't sound exactly the same I don't think, but I have the same thing happen upon deceleration, I will hear a thump, and sometimes I hear some light clanking when speeding up from coasting, or after taking my foot off the pedal.

I'm gonna keep an eye on this thread.

Rest In Peace Mom.

I had lots of old fords and they do this. Its the U joint going bad. I never changed them though, it don't seem to get worse.

I am also curious.

If I put my car in park I can roll it forward and backward a good 2 inches before it stops. If I jack up one of the rear wheels I can move it about that far before it locks; the drive shaft only moves a few degrees, and even then only during the last 1/2" of free play.

I also had the "thunk" symptoms above when I had my first program which kept the TC locked full time in 3rd/4th gears.

When I took the original pumpkin out of the Red Cougar, it had ~180° of play before the driveshaft moved. It was really screwed.

The new one had very little play; maybe 1" of rotation...

i dont think it backed out cause i like to use blue lock-tite(in case i have to remove it again) but i did replace the driveshaft to differential seal on it and wasn't to sure how much to tighten that nut(i just eye balled it). u might be onto something. is there a way to check this? what is the correct way to tighten that nut?

I'm watching this too. My car's at a shop right now. With my car, at moderate city speeds, I can almost make the clunk happen at will by lightly applying and releasing the throttle. But this happens no matter what driveshaft or u-joints I use. This is a different issue than the forward-reverse snap sound. Sad that the u-joints on these cars are good for only 3 years.

suspected of the spider gears and replaced them took half of that clunk off and it took care of another problem i was having. when going in the fwy in a curb and accelerated, i use to feel like a pull to the side on the back that made the car feel unstable. i thought it was a suspension problem but it was actually play in the spider gears. on a curb that play would apply power to one wheel then the other(fraction of a second)

the spider gears located iside the carrier here is a pic:

i also checked the preload on my ring gear and i think thats where the other half of my clunk sound is coming from. with oil i measured 12/1000" thats the limit without counting the oil i guesstimate like 14 or 15/1000. since i have to replace the gears im seriouly thinking about some 3.73's

I went with 3.27s from the factory 95 3.08s and while it was an improvement, its small. I'm going to go with at least 3.73s soon.

Might be your TC. Your description sounds similar to the clunk I have in my drivetrain and I think thats where mine comes from. I've noticed that when the TC is locked (at cruising speeds) and I accelerate or give the throttle a quick blip, it will clunk. However, when the TC is unlocked and I give the throttle the same blip, it doesnt clunk. From what I understand its pretty common. Pretty annoying too though.

Glad it sounds like you got your clunk fixed. Before you tore into the rear end, I was going to suggest that you check all of your mounts really good. Motor, tranny, cross member, ect.

I had a clunk and vibration on my tbird I couldn't find the cause to. It turned out to be my differential mounts. I replace them and no more noises or vibrations since. My car came with 3.08 gears which I upgraded to 3.73. It really changed how the car drove.

Well I'm joining this club. I too have play front to back and front again.
I have 4.10's from a cobra and I also have a markviii DS that probably needed new U joints.

Edit, My car is quiet again, no more clunking or popping. I just swapped diffs and my car is smooth again.
ohh and I still left a couple nice two tire marks on the ground with an open 3.27 diff.

same thing, pretty sure its the Ujoints, and the 2piece shaft coming apart because of the 1-2 spring delete in the Jmod.

but i also can rotate one wheel around 1/2 to 3/4 of an inch before the other side will move the other way on my open 3.08's.... guess I'm going to be in the market for a MK8 one piece shaft, ujoints, and a T/L with maybe 3.55 or 3.73. 'sigh' wish i had money

70% of my play went away after the 3.73 and Mark driveshaft swap. The rest of the play appears to be in the halfshafts.

My 95 had 3.08s and it was my understanding only 96/97 came with 3.27's.
