4 litre facelift cherokee
I have had a doning under heavy acceleration or steep inclines
Tends to die off when less torque is required
After a diagnosis the noise has probably been narrowed down to my transfer case
this noise did not seem to start until I replaced my exhaust which is what I thought that was original problem
When I replaced my exhaust I had to reweld the bracket on the front pipe directly before the CAT
This locates into a rubber mounting which is riveted onto the transfer case mounting
(I have drained the transfer box, the fluid looked ok but I did replace it)
Any ideas
