salford Posted June 12, 2007 Share Posted June 12, 2007 I've had the start of what I thought was a grumbling wheel bearing for about 50 miles now.I've ordered a new bearing and was going to attempt the job at the weekend. However, I put the car on axle stands last night and had my mechanic-neighbour have a look. The wheel that is grumbling is not spinning ad freely as its opposite number and generally, it feels tighter.I rebuilt the rear suspension a few weeks ago and although the hub nut was torqued up as per the manual (115 ft lbs) my neighbour suggested slackening off the nut a smidgeon, as he felt that it might be done up too tightly.I'd be grateful of some ideas as to weather it is likely that these symptoms would occur if it has been over tightened, or if I'm being too hopeful and should get on and change the bearing.Cheers,Steve Link to comment Share on other sites More sharing options...
neilnaz Posted June 12, 2007 Share Posted June 12, 2007 It sounds like it has been over-tightened and may have damaged the bearing. You may get away with re-doing the bearing. They should be tightened until there is no play then backed off to the first possible point to 'get the pin in' the castellated nut. Over-tightening can cause bearing grumble and possible damage. ::)Neil Link to comment Share on other sites More sharing options...
salford Posted June 12, 2007 Author Share Posted June 12, 2007 The GT is a rotoflex car, but I put the spacers/shims back in exactly as they came out, so I'd hoped that the end-float wouldn't have changed too much. Link to comment Share on other sites More sharing options...

99176 Posted June 12, 2007 Share Posted June 12, 2007 It would be worth trying an additional shim ( 3 thou )but if you have to rebuild ,it's a lot easier on a benchthan on the car. Link to comment Share on other sites More sharing options...
