What puzzles me is that GU is heavier than GQ. Yet, they installed a 4:3 LSD(rear) with a clutch pack half the size of GQ one.
I wonder why they thought a seemingly weaker LSD in the rear of GU is ok for a 4WD?
Length of the rear axles between GQs and GUs are pretty much the same, as well as the drive shafts(GU's shorter?)
So, it doesn't make any sense to me that the new factory fitted GU 4:3 rear diff is weaker than the GQ one.
GUs 4:3 rear LSD's clutch pack is so small, the diff can easily be mistaken for an open diff, rather than an LSD.
Any thoughts guys?
'cos if I'm to be told the GU rear 4:3 LSD is as strong as GQ one, I won't bother finishing the half finished rebuilding job of the GQ rear diff.
(It's a job better left to a specialists, but I got onto it and acquired all the tools, thinking it will be fun, but it hasn't been)
It was the stuffed up pinion bearing. But, since I've dismantled it to pieces, I won't have a choice but, replacing all the bearings and setting the preloads and backlash, though I'm not
planning to dismantle the clutch pack and replacing them(assuming they are already good) or setting spider gear backlashes.
So, in reality it's a less than half a rebuild job.
But, I don't think even a diff specialist would dismantle spider gears and clutch packs for a repair job that only need to replace the pinion bearing and set the pinion bearing preload, or do they do the whole thing anyway?
In my case, I was pretty sure, I could get away with simply replacing the pinion bearing and setting the preload, but ended up dismantling the side bearing s as well. But, it would be a waste anyway, 'cos it was not possible to buy just the pinion bearing.
They all come as a kit, which includes the pinion bearing and the side bearings.
