Very lose bolts on hub, now diff issues
Discussion
Gents,
At a recent MOT, the tester noticed grease around the rear OS wheel hub but no tear in teh CV boot. We looked at it together and found that one of the allen bolts on the back face of the hub near where the drive shaft enters the hub was so loose it had around half an inch of thread showing. The other 4 or 5 bolts were also loose. I have not had to dismantle the driveshaft or hubs yet so am not familiar with the construction or what these bolts actually do or whether them being loose could cause loss of grease.
I did have the differential changed last year by a well known TVR independent so I am guessing they forgot to tighten the bolts.
I assumed if these bolts had come right out, the half shaft would have come out from the hub.
So glad the MOT tester noticed it before I had a half shaft whipping around under my backside ! That could have been very nasty.
Oddly, since tightening the bolts, the diff now feels very clunky when doing anything other than going in a straight line but especially if rolling relatively slowly with no power applied in neutral. Feels a bit like when the limited slip is coming into action at very slow cornering speeds.
Can anyone advise how tightening these bolts could affect the diff and if the loose bolts tie up with loss of grease.
Thanks.

Thanks. The bushes were changed with the diff and I wouldn't expect tightening the CV / hub bolts to suddenly cause them to be problematic.
Having lose bolts at the hub end wouldn't make the diff operate any differently would it, e.g. allowing slip there rather than through the diff ?
Will check the oil as the diff appears to be leaking as the exhaust is always wet below it.
