Hi All,
I've read a few different threads with dozens of possible reasons for driveline clunk. Hopefully my symptoms might help someone give me a a few more specific pointers on where to start.
UZJ100 is low miileage (100k kms) RHD with a Slee 2.5 lift and front diff drop, but no panhard correction (bar is only 2.5" above parallel on the body side). Aftermarket 33" x 12.5 wheels are silly heavy at 100lbs per corner (on the list to go back to thinner 33s on OEM rims when tyre prices normalize.).
Clunk 1. happens when I roll over a speed bump, and apply the throttle (even gently) before the rear wheels have come down the offslope. If I roll over completely off throttle, then accelerate after, then no clunk. But if the rear wheels compress slightly under acceleration as they leave the speed bump, then the clunk is there!
I was wondering if even the tiny sideways movement due to the panhard not being flat level might be causing a bind - all ideas welcome, or if someone has has this same exact issue and solved it!
Clunk 2. is much lighter, and feels like somewhere in the steering column. On tight right turns over bumps, or when unlocking steering lock, there seems to be a bit of loose play and little clunk as something moves near right hand lock, and takes up a small amount of slack under tension. Again, any pointers on where to focus attention would be great. I've tried moving the rack etc. and seems solid from underneath.
Thanks for any help in advance.
