How to replace the rear diff mount (pics)

Postby Meurz » Mon Jan 15, 2007 12:29 am

I fitted my C-One rear diff mount today, so naturally, I took pics! :)

I was able to use the 2 post lift at my mates work, which makes this mod a LOT easier I guess. I don't want to think about the idea of doing this with the car on the ground.. :wink: To get the old diff mount out, the diff needs to be moved forward and slightly downwards a bit. First step was to soak 14 bolts in WD40:

Image

There it is, the stocker (unbolted already in this pic):

Image

While unbolting the diff itself, I noticed the holes in the diff case are significantly larger than the bolts which go through it. Therefore I marked the diff and chassis to prevent vibrations (and stress in the drivetrain) caused by a wrongly aligned diff later on:

Image

With the help of an extra support we lowered the diff a little bit so I could wiggle the stock mount out.

OEM vs. C-One (Looks nice and beefy):

Image

Next up; slide the C-One mount in, raise the diff and bolt all parts up again. The new mount in place:

Image

And what a difference it makes! When I lift off the throttle when driving, there are no nasty clunks and weird sounds anymore. All good for the next couple of years and km's! 8)

OK, nice job as always. Question, where can I purchase the C-One mount?

I pulled my rear diff with just jackstands, lying on my back. It actually wasn't as hard as you might think. So there's hope for all of us without access to a proper lift :) BTW, nice write up with excellent pics.

i also did mine on jackstands. it just takes a little longer, and you might get some rust/crap in your face.
