While trying to find the source of a bad rumble, I recently replaced my front wheel bearings. I could swear the rumble was coming from the front and only later discovered it was the rear diff ! Not wishing to lie on my back in the drive to do the job, I got an indy to fit a new diff.
The car is running OK now but I thought I would check out the rear hubs and brakes which was not part of the indy's job.
I am not entirely happy with what they have done. They fitted a refurbished 2 pin diff without asking me and managed to round some of the bolts holding the hub carrier on.
However, one thing I noticed is that they have used sealant on the joint between the hub carrier and the rear axle. They are machined faces with 6 bolts.
I can't see the point of using sealant as the oil seal keeps the oil in the axle. There is no mention of using sealant in Rave.
