Hey all. Here's one of the two symptoms I am planning to fix.

When driving down the road and I lift off the accelerator/gas pedal, i feel a one-time subtle but noticeable jerk in the truck. I dont know if it's a motor mount, drivershaft universal joint (I had this problem on my last car and replaced so I've seen them when they're bad but these aren't bad--only a minor amount of moistness around the seal(s) of joints). They look to be in good condition. I also noticed I felt it slightly more after changing the exhaust. I was thinking maybe motor mounts are bad, but i didnt know if there was looseness in the driveshaft caused by those joints and that would be what's causing it, or something else.

Thanks!

What I do to check mounts is to have someone put the rig in gear while I look under for anything moving. May need to give it a bit of gas to check tranny and motor mounts, but with a firm foot on the brakes, you should be fine.

check differentials, any play in a UJ can cause this too
but i did note the exhaust replacement, maybe your have resonance comming back up the pipe

That's what my indy told me, my decatt is the cause. I hope i'll find time to put straight tubes instead of emptied cats

There's your answer, emptied cats dont help at all

Just came from my friendly mechanic at the Land Rover Stealership. I just purchased the truck a month ago and needed him to totally go over it. I have to say Lou (shop foreman) really knows his stuff.

he checked the rear diff and there is some minor play in it. he looked to either the universal driveshaft joints and then to the diff. as the two in front have been replaced, the only other option is the two rear. so, i'm going to replace those this weekend and then we'll see if the diff is causing that. He did say you know when the diff needs to be rebuilt because the chain will develop so much play that it starts to make a hell of a noise upon acceleration. Hopefully this helps anyone in the future with their symptoms. Stay tuned to see if there's any improvement once I replace the old U-joints.
