Thread-lock for rear suspension arms
Assuming the 4 upper & lower arm-to-subframe bolts need thread-lock, what's the trick to getting the bolts in without scraping it all off on the bushes?
Or do they need thread-lock at all? |

I just checked the old factory arm-to-subframe bolts that I took out and they don't have any thread-lock.
Neither do the 4 old factory subframe-to-body bolts. |

I’ve never used it at all on these bolts.

The captive nuts are Nyloc
Plenty of coppaslip on the plain shank of the bolt, none on the threadform |

You don't need thread lock. However if you did it would stay at the bottom of the threads and not scrape off during assembly.

The bolts supplied new are not Patchlok so thread locking compound is not required. The captive nuts are Nyloc, so technically are single use, but to be fair who is going to replace them. My advice is to box it up, then with the weight of the car on the wheels, torque up the pivot bolts to 90 Ft/Lb and not to worry about it None of the ones I've done so far have fallen off Brian |

Maybe a Spring locking washer would be of some help. The ends might dig in and offer some resistance to undoing. -- That would be metal to metal.---- |

I've already got a tub of Comma Copper Ease - I suppose that'll do instead of Copaslip. OK, I'll try doing it that way, although I'm not sure I can physically get at the bolts when the wheels are back on because the car isn't high enough off the ground to crawl right under the floorpan. I can't lift it any higher because my trolley jack had already reached full tilt getting 3 layers of wooden sleepers under the sill jack points. (It needs 4 layers to be able to crawl under the floorpan). |

Don't know if this helps but the wheels don't have to be on if you are supporting the cars weight on the suspension. ( Blocks of wood underneath. ) |
