This is my first TechTalk thread, so be nice to me.
I think I may have the off side rear wheel bearing going on my 2007 S3 (metric chassis, 1.6 K-series). I had it go at 2000 miles/9 months, and when it was removed a couple of the rollers had fussed together! Caterham sent me a pair of bearings, but I think I'm getting the same squeak again.
As an observation, when putting the ears on to the dedion, the near side ear was almost perfectly positioned and touching the end of the tube. On the off side, it was probably about 8mm off, which got squashed up as the ear is bolted in place. Surely this leaves a fair end load on the bearing.
I've checked that the diff is centralised, and it is (38.5mm from unused mount to the inside of the chassis rail on both sides). From the inside of the chassis rail to the edge of the DD ear is 11.3cm on the N/S, but only 11cm on the O/S.
Is this normal? And why is the O/S driveshaft longer than the N/S? My measurements would say they should be the same (unless the output shafts of the diff aren't central)
Any suggestions warmly received.
