I'm not very good with gears but I'm getting a hell of a jolt when I take off and then again after stopping like something is settling? It's hard to explain smooth as glass when I drive. Also when I pull a load, it doesn't do it as bad. I took the cover off hoping the mains were backing away but no such luck. The clunk feels like a bad u-joint would feel but without the sound...? Lost

I have the same thing...mine is only when it stops. It feels normal when taking off.
I've heard it's the slip yolk but I don't buy it

The squeaking is my rear brakes, I think..sounds terrible

It is in all likelihood the slip yoke. the slip yoke splines on the 2 pc shaft's are prone to need grease and will cause a thunk clunk when you first start out from a stop and some time's when you stop. my solution install a grease Zerk in the slip spline problem solved

I dont have a 2pc shaft. Its an aftermarket 3.5"

I had no idea the driveshaft moved so much..

I can't believe all it took was grease?

jferg92

So you just greased the slip yolk?

fordmotorsport

Yes, stupid right that for the last two months ive been putting up with that clunking when the simple fix. Just take the driveshaft off and load some grease in that boot then I greased the shaft too.

Well looks the slip yoke advice I got was right. Who'da thunk it..
