Tightening Suspension Bolts

[Lewis's Friend]

Hi All

Quick question, following on from my previous question regarding polybushes. I have now decided to go for OEM bushes, but this leads on to how to fit them.

My car is up on axle stands, and I'm wondering how best to get the suspension to normal levels before torquing all the bolts up. In an ideal world, I'd bolt it all up loosely, put the car on my 4-post lift and torque it all up. Sadly, I don't have a 4-post...

So as a compromise, could I use a pair of jacks on the front hubs (for example) to lift the car fractionally off of the axle stands so that the weight is going through the suspension and it is compressed, then torque the bolts? I'm guessing that this does not exactly match normal ride height, but would it be close enough? Or is there a better method that I've just not thought of?

Any help appreciated.

The bolts that matter are the ones that prevent the bushes from twisting as you lower it onto the wheels, for example where wishbones mount to the chassis. What is stopping you from putting the car on its wheels before you tighten these bolts?

I think I'd struggle to tighten them with the car on the ground, particularly the front ones where access with a torque wrench would be pretty tricky. I'm not sure I'd have the clearance.

These are not usually highly stressed bolts and the exact torque is usually not critical. You need to know how much torque to apply, but you should be able to get it close enough without resorting to a torque wrench. Assuming you use an ordinary spanner, can you get to the bolts OK?

I'll have to see. Where its double wishbone, I think I'd struggle to get to the top bolts with the wheel on even if I could access the lower ones.

Plus for my peace of mind I'd like to use a torque wrench if at all possible...

Cheers for the feedback, all appreciated.
