Nuts & bolts questions
If/when the rain dries up I'll be slackening off the rear suspension nuts & bolts (all of which are new) and then re-torquing them with the weight of the car on the suspension.
Bearing in mind I'll only be slackening off a couple of turns, can I re-use nuts 5 & 9 here and 6 & 8 here - or should they be replaced? Bolt 3 here came with pre-applied locking compound. Can I slacken it off and re-tighten it without applying more? (If I remove the bolt to apply new compound, nuts 9 might have to be slackened off too and maybe replaced). And while we're here my rear ARB is the 'uprated' RGB101062UR. The two rubber bushes don't close up completely when the U bracket bolts are done up - they look like this instead: I don't remember a gap like that on the old ones. Perhaps the hole is too small for the uprated bar? Btw, RAVE says lubrication must not be used the bushes - whoops! TIA. |

I just measured the old ARB & bush (the ones I took off) and the new ARB & bush. Both bushes were measured off the car.
The old and new U brackets are the same in profile - i.e. there's no difference in size or shape of the U. Unless there's a third bush we don't know about (one with a bigger hole than RBX000180) I can't see how to solve the air gap. |

Personally, I would re-use the nuts identified. They're standard flanged nuts. If they were self-locking type I'd renew them.
I suppose it depends on what type of locking medium is used for the locking band. If it's a metal catalysed full polymerisation type, it will not perform as before once the 'lock' is broken. A lower strength medium may accept a 'second chance'. I don't know enough about thead locking chemistry so I really don't know what the answer is. TC |

I'll go and have a close look at them all later (it's raining again). Meanwhile, just for info, I think nuts 5 & 9 and 6 & 8 are all 'stiffnuts' (as per Brian's posts 3 & 8) in which case they should probably be replaced. And bolts 3 have red locking compound as opposed to some other MGR bolts which have blue - I've got no idea which colour means 'use once'. Maybe I should just replace the whole lot and be done with it - I don't want to have to keep crawling underneath to check the darned things. There again, it's another £30 or so down the drain. |

Not at all like front suspension arm bushes or lower tie bar bushes.--- |
