Engine/Transmission (1998.5 - 2002) Driveline grumble on de-celeration

[johncameron]

I've started noticing a slight "grumbling" when coasting on the highway. It seems to happen when the driveline is right at the "neutral" point meaning it is not accelerating or decelerating. There seems to be more driveline slack also.



What should I look for.



Thanks in advance.

u-joints in the read driveshaft. mine did the same thing. no load on the joints allows them to move around in their bores if they are a bit worn. climb underneath and twist the driveshaft by hand (PARKING BRAKE ON, WHEEL CHOCKS, BE SAFE!!!) to see if there is any play in the u-joints.

Sounds like worn U joints to me too.

There is a fair amount of slack in the u-joint by the diffy. Thanks for your help guys. I'll report back once it is changed.

I ended up changing the yoke, center bearing and U-joint. All is quiet now.
