Replacing diff

Post by Wafoo » Sun Apr 22, 2018 8:28 am

Not confirmed yet but top of the suspect list.
How easy is it to change the diff on one of these?
Seen lots for sale on fleabay but not many 2.2 ones, lots of 3.0 ones, will they fit off will the ratios be all to cock?..

If it’s got to come out it would be a crime not to put an LSD in there :(

It's about a 4-5 hour job first time round when using ramps. An LSD is absolutely great but I doubt you want to send around £1300 when you can spend £200.

For the use I get out of her can't justify an LSD, the plan is to use her this summer then go for a 3.0 for next so really don't want to throw lots of money at the girl
So any diff will fit?

Probably. It's largely the same underneath. Check realoem. Part numbers should be the same.

The diffs are all different ratios across the range.

You need this thread

Mike (ducklakeview) posted a table of ratios if I recall

Great chart but doesn't mention the 2.2i, is it because it is not worthy......😣

Took me about 90 mins to get mine out, less to get the LSD back in and would be faster next time. Bear in mind my exhaust etc had already been off a few times so no fighting with the downpipe joint, and I have a lift.

That's pretty good going. I suspect a few of the older members on this forum struggle to get dressed in 90 minutes never mind getting a diff out
