Torque settings on rear suspension

[JohnFol]

Morning all, just refitting rear cross member to chassis and Haynes give 24.5Nm as the torque setting. This feels way too low. (79 spider)
Any advice?

Go with the Transverse Link settings they are the same size fasteners and even the same thread pitch. Use new P type (Deep) zinc plate Nyloc nuts and thick washers to spread the load.

I happened to buy deep nyloc and new bolts for outer ends of transverse arms so I have a few spare.

Although bush issue now resolved, cross member still shows some flex when grabbing wheel (whilst off the ground) and rocking it at 3 & 9 o'clock position.
Can't be sure if this is 1 more issue to solve or typical of the car

Hi John,
Remember to have the wheels 'on the ground' when torquing up.

I just had a look in the technical databook and it too says 24.5Nm so that's where Haynes got it from. That has to be a typo - especially as it says to use torque wrench 88091135 which has a range of 29 to 137 Nm

Thanks Stuar

Nigel, Interesting....
Working alone and don't have access to a pit or lift so working under the car whilst on axle stands and clearance is ok. Couldn't imagine getting access behind the road wheel or inboard bushes without it being raised.

 I'm using the infallible Haynes guidance and the suggestion is to effectively load the suspension by jacking under the roll bar, effectively lifting wheel off the floor.

I'm open to a better way...

Yes John, that will be sufficient.

This pretty much applies to any metal/rubber bush that will sit 'clamped',
i.e. minimal rubber stress during normal operation.
