108 loose bolts

Post by andy6409 » Mon Aug 11, 2014 8:16 pm

I have had an annoying rubbing/squeaking sound coming from my nearside front for a while and it started getting worse so I finally decided to investigate

When I spun the wheel the brake disc was rubbing so I stripped,cleaned and de-rusted everything but it was still noisy :(

I noticed that there seemed to be some staining coming from between the star and rim and when I applied pressure to the star I felt movement ,it became apparent that quite a few of the bolts were loose so I decided to strip the wheel
I found that half of the threaded holes had up to 1/4 inch of compacted blasting sand in them which must be from a previous refurbishment
Holes were cleared, wheel assembled, bolts cleaned, thread-locked and torqued

I now have a quiet car again :D

Did the bolt heads not look raised from the star?
Sounds as if they were tightened up onto the silica sand which subsequently dislodged or moved .
I sincerely doubt properly tightened bolts would ever work loose , Once tightened & left for a while they can take some shifting with the difference in metal & also the pressure once tyres on & inflated .
I have also had a set previously that appeared to have every bolt glued :evil: not good from removal point of view
