MenaceXR6 New Member 5 Member For: 8y 6m 10d Posted 19/08/18 04:09 AM Share Posted 19/08/18 04:09 AM just need to lower it, however im still after that correct bolt, I dont know anyone that stocks a high grade bolt and im not going to ford for it, so if you know that'd be helpful.

I've done all kinds of high powered driving and mine hasn't broken. If we rule out driver error then it probably is an issue with the alignment of the diff or associated parts. Your diff bolt should not be breaking with the power levels that we've talked about. Link to comment Share on other sites More sharing options...

I've stripped my thread ever so slightly but will I run into issues if I tap a larger m18 bolt in and drill out the centre of my rear diff bush to take it ?
