Daneo 330 Member 14 Member For: 15y 3m 13d Posted 14/09/09 06:02 AM Share Posted 14/09/09 06:02 AM Recently I had raped the stocko rubber Centr diff mount out and changed it out put in a new Urethane one from Fulcrum, since iv done that the bolt came loose and I started getting diff thumbs so I had a mate look at it and tightened it back up, but after driving a few more k's its come loose again.... Now iv read somewhere on net that u need to possibly change the bolt when u put in an aftermarket bush but no idea where or what type to get! has anyone done this before and had the same issues?????? Advice is appreciated, thanks in advance Link to comment Share on other sites More sharing options...

Do a search on "class of fit" to see what I mean ie class 1, 2 ,3 etc. Link to comment Share on other sites More sharing options...
