clunking everytime i shift

[5literstang]

i hear a clunk everytime i shift...u joints?

 

[Brute03]

i get that sometime when i go from 1st-2nd or 2nd-1st, it's like a thud

Driveline slack possibly.

In all manual transmission cars there is a small amount of slack. With manual transmission and clutch practice you will not feel NORMAL slack. If you have anything beyond normal, you will not locate the problem on an internet forum. The only way to locate the problem is to safely raise the rear wheels, get under the car and start turning things back and forth 'til you find the slack.

What clutch? Hopefully it isn't the OEM one with an s-trim.

thats what i was thinking orginally, but someone told me that it could be ujoints, im jsut going to replace them and check for slack

time for a louder exhaust, then you wont need to worry about the clunking

Could be your U joints,jack up the snake,and twist the driveshaft back and fourth by hand,and watch the U joints while you are doing it.If that is good,and they have NO play in them,then it could be your trans.

I've made this interesting discovery in my car, that has been the same in two other 'Stangs. I had a bad clunk, and could never figure it out. I put in a new clutch, flywheel, throwout bearing, pilot bearing, pressure plate, shift fork and ball, u-joints, all new bearings in the rear end, and a perfect lash adjustment, and still had a clunk on shifting. Turned out to be the upper control arm bushing, where it mounts to the body. The inner steel piece that the bolt went through was too wide, and when the axle would move, it would clunk up there. I had a friend kick my rear tire from the back while I was under the car, and I saw the thing move. I'd check your UCA bushings, because this has been the same on two other Mustangs I have worked on.

 

[5literstang]

i have an IRS tho

 

[Yellow2002GT]

I have the same problem too! Mine is and Auto and found out it was the UCA's also........If your suspension moves too freely or binds you will have noises!

yeah the ujoints seem to be good but there was a little play in my driveshaft..
