Hi guys. I am looking for some advice.
When i accelerate from stand still i (often) get a "tok" noise from the rear of my Def90/98. Sounds like one metal part hits another one. When the car is cold, it does not happen or it is very difficult to reproduce. After about 10 minutes driving, it starts happening when i take off.
There is no noise when changing gears, neither up or down. Also not when I get off the throttle to "provoke" load change on the system. it is only when i start off.
First i thought it was a worn UJ in the rear prop shaft (had also quite strong vibrations starting at around 40mph). Prop shaft is sorted now, vibrations gone, "tok" noise still there.
Running out of ideas, but here options that fellow LR owners came up with plus my thinking:
- Differential: possible. bearing, pinion etc.
- A-Frame ball joint: Would this depend on the "temperature" of the system? Would say no. Would be there all the time.
- Bushes: Sames as ball joint ?
- Transfer box: Latest theory (expensive one). But I would hear the noise not at the very back, more likely to hear it more or less under the seat?
- Drive shaft / drviving member: worn splines
Any ideas from you side?
thanks
