[928uk] S4 Suspension refresh?

[jonathan at netvue.co.uk]

I did suggest 10 miles, and in hindsight that distance suggestion was a bad idea.

 

I will be doing this on my own car over a much shorter distance and then the final torquing to spec.

You suggested doing it for 10 miles! Just admit, it's a bad idea.

LOL! How does driving carefully a little specifically to settle your suspension equate to going over a few potholes!!

 

If someone follows my suggestion and chooses to drive on public roads and then has an accident that will be their own fault, or that of the third party, nothing to do with bedding in a tightened but not fully torqued suspension.

How tight is "Not fully torqued"? I would say that a fastener not fully torqued is likely to become loose after a few pot-holes.

Unless you can specify torques, I don't think you should be suggesting it, and unless you've tried it yourself, I wouldn't follow it.

And if someone follows your advice and has an accident?

I don’t believe anyone said anything about leaving bolts loose Smiffy.

 

Not fully torqued and carefully driving a little, were the words used.

 

I agree that we could add “done up tight enough to maintain the wheel alignment” as you feel that needs clarification.

If a bolt is loose enough to allow things to move, driving is not going 

to be safe, it won't maintain the wheel alignment , and there is a huge 

risk of things getting looser over every bump.

 

If you can go up and down your drive at 2 mph, yes, a good idea, but I 

wouldn't venture onto the road, or go above 10mph without everything 

done up tight.

Advice I read on rennlist suggested carefully driving a little before fully torquing the front suspension bolts. I can see the logic behind that: If the front suspension bolts are fully torqued immediately after you lower the car onto its wheels the settling later will twist the rubber bushes (inside face relative to outside face), because they are clamped tight and have no freedom to move. Perhaps it’s just a nicety and one that most people won’t bother with.
