Hi Guys
Looking for advice on what specific bolts to tighten up on the rear of the Paj to solve a thunk? Have been reading up some posts and the suggestions are the rear wheel bearings and some bolts on the diff but I don't know what bolts? I have the Paj in the shed this weekend to fit the new Kaon Bash Plates and while I am under there and the tools are out I might as well torque up any bolts that may need it. Would appreciate any advice here otherwise it will be the Haynes Manual and a torque wrench for every exposed bolt...![Dunno[1]](https://www.pajeroforum.com.au/core/smilies/0/0/5/4/3/6/images/smilies/dunno[1].gif)
When accelerating onto the highway I have started to notice a thunk in the driveline from 4th to 5th, and it seems to be less so in 3rd to 4th gear changes but not as noticeable as in 4-5th.
Also would the rear bearings leak water into the diff if they were slightly loose? Interestingly the workshop recently said they needed to change the rear diff oil as it looked like it had water contamination. I had changed the diff oil myself just before last summer ( no evidence of water then...?) and also installed diff breathers front and rear as we launch the boat deep almost every weekend in the summer. Since the oil change we have done a few deep river crossings in the Vic High country and the diff oil still seems fine but moving through the water is different to parking on the ramp loading the boat..
Cheers
