hi everyone can anyone pls tell me why on of the bolts would be loose what causes it?

once tightened is it ok? or is it something really really bad?

regards

 

sorry i meant why one of the bolts^^^^

 

I'd suggest simply re-tightening then checking occasionally, until you're satisfied that it's going to stay tight.

As to cause, perhaps it was miss-tightened at some previous maintenance point... or better minds here may have more informed suggestions.

 

thanks buddy jus hope thats all it was a mis tightened like you stated, and not a fault will drive for a week and see if it gets loose again

regards

 

Also, check the rubber flex couplers for cracking or aging.
