What bolt and nut on Ball Joint??

[s2_bo]

Hello,

I when to have my wheel alignment done today and it all started off well, The place i used had one of those fancy radio wave guided alignment machine that picks up on just about everything that could possibly be out...

After about 40 Min's of 3 to 4 of them adjusting the wishbones and cambers
(It was dam scary letting all those mechanics near the S2 - as they are only used to chaving up kev cars. )
they decided that the bolt that joins the Ball joint was not the correct one. In all fairness this did not look like an OEM part to me and my only guess is that when i had another garage do the wheel bearings not long ago they replaced the bolt with a standard non hightension one.

At this point they stopped and said that there was no point in carrying on until i had the correct bolts fitted, as these ones would not last very long etc. so it would just be £60 for 4 wheel alignment down the drain..

Does any one know what bolts should be used to connect the ball joints at there lowest point? (Ill try to get a pic in the morning of what is currently on there.)

Thanks in advance..

You mean the one that clamps under the ball joint to seal it in its socket??

if so I just fitted a standard high tensile stainless Nut and Bolt of the correct diameter (not form Audi)......No Problems with it.......

What was "wrong" with this bolt?

[s2_bo]

Yeah thats the one i mean. Apparently the bolt is slightly to thin and threaded all the way through, resulting in weakening, a bit of give, and possible failure in the future.
(This is what the guys at AMS said anyway.) But then they might have been trying to get out of doing the alignment as it was taking the ages - If others have used normal high tension bolts then maybe it will be fine.

Cheers s2dude.

Depends if you are talking about front or rear and the year of your S2.

For the front N 010 445 7 bolt and N021 195 5 nut for cars up to chassis 8B-P-008000

For the front N 034 778 4 bolt and N021 195 5 nut for cars after chassis 8B-P-008001

Rear uses N 010 445 7 bolt and N021 195 5 nut for all chassis.

Bolt is M10x1.5. 45mm long and 20mm unthreaded section for the early version
Bolt is M10x1.5. 50mm long and 24mm unthreaded section for the later version

Thanks Mike!!
thast a big help, ill get thos bits orderd asap.

Thanks again.

S2 Bo// Its only a nut and bolt just needs to be correct size. Audi charge out royally for their

"speical"bolts.....

a good ironmongers will sort it

??? No they don't.

considering what the bolt does "any old bolt" will not do especially stainless steel, it may look pretty but doesn't have the strength needed.
Use the correct grade of bolt, any 8.8 grade of bolt (and make sure it is a bolt with an unthreaded portion where is passes through the stub of the balljoint) will do and be safe in the knowledge that you havedone the job correctly.

Thats what I meant by matching it up correctly. Though I do have access to a hell
of a lot of bolts :mischeif:

Use a socket head cap screw, they are only ever made out off at the lowest 8.8, then 10.9 then 12.9 super tensile jobbies.

Thanks for all your input guys.. Stop on as always .
