does rear wheel bearing need replacing ?

[richard s]

last mot i had an advisory for play in rear wheel bearings i have just gone to tighten up a bit to see if it takes up the play then rocked disc from top to bottom and could hear a squelching sound from back of disc does this mean that the dust seal is knackered
if so am as well getting a set of rear caliper to carrier bolts for when the bearing gets changed or is there a way of getting them off without them being a bstard
do i need anything other than discs/bearings/pads
cheers

Sounds like bearing to me, you will need new bearings anyway as they are pressed into the discs.  With the caliper bolts id say you are better to soak them in wd40 overnight first as they are a bit of a bugger, I nearly knocked myself out with my bar they were so tight on my old 8v  :embarassed:

cheers i think i will order some bolts aswell due to the averages of sods law

Use Plusgas or another brand of proper penetrating fluid instead of WD-40, which will have about the same effect as p*ssing over the bolts.

where can i get plusgas from
cheers

WD-40 worked a treat actually

My brother in law said they used Coke to loosen bolts in SA.

Used to use coke to clean the toilet when I was a student, works a treat if you leave it overnight!

Anyway, this should give you all the info you need, found it on the forum somewhere when I did mine:

The only thing I'll add is that I found it a lot easier to wind the pistons back after clamping open the rear bias valve

Hmmm pretty sure rears aren't pressed in, fronts are but rears.....

there should be a little play in the rear bearing, jack the car up and hold the wheel top and bottom, push and pull, there is supposed to be some play, not sure the correct amount though! I would have thought no more than a few mm play though. The squelching sound is probably the greese thats in there. Check good old Haynes to strip the rear bearings.

The rear bearings are cone and cup affairs. The cups need to be pressed in. But to be honest, the bearings may just need serviceing. If they don't growl they should be ok. Remove the calipers, then the disc and the bearings. Wash tha bearings out in fuel or something similar and make sure they are not damaged. Discoloured bearings are perfectly acceptable, but any coating missing. the bearings need to be replaced. Also look at the cups and make sure those are not damaged either. Then grease the bearings and put them back together.
When tightening up the hub nut, do it up tight whilst turning the disc until the disc is difficult to turn. This will seat the bearings. Loosen off the  hub nut and retighten until the disc starts to drag. Check for play and adjust again. Then fit the safety cap and fit split pin. Fit caliper and wheel!
Once whell is fitted, rock it to and fro a couple of times to make sure there is no play. Job done.
Should not take more than an hour a side in your garage or on the driveway.
