Suspect diff ?
Discussion
Hi all, I think my diff is starting to give notice, I had a whining and rumbling from the rear, now I already had new c/v joints to fit so, I`ve checked the u/js, fitted the c/vs, checked the wheel bearings and changed the oil in the diff. It was a bit better but I think a replacement diff is reqd. Is the diff easy to get out ? I`ve carried out a diff swap on my S2 and that was staightfoward enough. How is the BTR diff bolted in and does it drop straight out ? Thanks in advance for any help.
If you've removed one before its sounds like you know what your doing.
I've recently replaced mine via an experienced Tvr owners workshop and facilities.
My observations would be good tools, impact gun, two people makes life lots easier.
A few bendy spanners etc.
Dis connecting drive shafts- straight forward enough
Prop - 4 bolts.
Rear top bush bolt. Long extension bars coming at them through wheel arches either side (two socket sets)
Disconnecting speed sensor - 2 bolts
The diff is suspended by two plates that bolt to the diff and then the chassis with the other two Dif bushes.
Impact gun here is priceless.
Start by loosening the two bolts top and bottom that connect the brackets to the diff, these bolts are threaded through Dif casing and nuts are applied to the rear. Very tight and rusty,
Impact gun first clockwise to push bolt in and take pressure off the nuts on the rear, this might help you get the nuts loose. Remove nuts and withdraw bolts out of Dif.
Can't remember off the top of my head but I think we got bolts loosened off then undid the two bolts that connect plates to chassis via bushes at this point leaving bolts in place, removed the bolts to diff etc taking weight of Dif on a gearbox jack throughout the process makes pulling the bolts out easier. You'll need to remove plates out the way basically and then lift front of Dif up and over brace bar on chassis forwards then rotate Dif down and draw left side out first as it's the shorter side.
I've bound to have forgot something so if anyone else has anything to add please do.

That`s great, thanks, it`s good to have some info before I start, I`m hoping the bolts are not to bad as the car had a full chassis refurb by a previous owner.
