Ok, thanks for doing that Ian. Can you remember which was the better fit, 111mm or 97mm?

97, the 111 was a bit of a fiddle. Also the 97 had the spring and ball bearing to keep the socket on. The 111 as it was "home made" was just a square end. The 111 will do, so if that is all you can get or something in-between it should be fine but then of course there is the thickness of your ratchet to consider, so the shorter one would be safer. jacking the trailing arm up to re-torque may not put the suspension in the same position as it is with the car on all 4 wheels. I put the rear end onto ramps, the front was on ramps also macafee2 |

I thought about this yesterday and tweaked the height of the front blocks. It's set up now so that when the back end is just lifting off the rear blocks, the front end is still resting on blocks but the whole car is dead level (as checked with a spirit level under the mid point of the sills). Isn't that the same as having all 4 wheels on and resting on the ground? |

RAVE - trailing arm torque confusion
While waiting for Amazon to deliver a 75mm extension I thought I'd see what RAVE says about setting torque on the trailing arm bush bracket bolt (#6 here).
I've set mine to 100Nm off the car because the bolt is invisible when the trailing arm and bracket are in situ. Before tightening the bolt I angled the bracket to the position I thought it would be in when the weight is on the suspension, but it was only a guess. This is what RAVE says on page 808 (Workshop Manual Service Procedures) underneath diagram M64 0112: 4. Position trailing arm bush bracket, align to marks on casing, fit bolt and tighten to 100Nm. Caution: Nuts and bolts must be tightened with weight of vehicle on suspension. What marks? Which casing? The only marks mentioned are on page 807, where in the left column it says: 14. Reference mark trailing arm bush bracket to body to aid assembly and in the right column it says: 15. Align trailing arm bracket with reference marks and tighten bolts to 100Nm. These obviously refer to the three bracket-to-body bolts and not the single arm-to-bracket bolt. So what the heck are they talking about on page 808? Have I missed something? And what the heck is diagram M64 0112? My trailing arm looks nothing like that. |

If you have already tightened to 100, I would loosen them off once you have the car on 4 wheels and then tighten to the correct torque. If you have had the trailing arms off then I would suspect you will need to have the tracking checked macafee2 ignore this post I did not see when I replied it was trailing arm, sorry Last edited by macafee2; 17th February 2020 at 17:03.. |

I think the referance marks is refering to marks made by the person doing the job made before dismantling?

This bolt cannot be torqued on the car - it's impossible because the bolt head and the nut are completely covered by that flat plate on the bracket. Quote:

This text on RAVE p807 is an attempt to get the bracket back on in exactly the same position as it was in before you took it off: 14. Reference mark trailing arm bush bracket to body to aid assembly. 15. Align trailing arm bracket with reference marks and tighten bolts to 100Nm. It doesn't work because the reference marks I made around the bracket (before I took it off) got obliterated when I cleaned up and repainted the whole area with POR15. |

All of which brings us back to here:
What marks? Which casing? |
