Getting ready to install coils and rear control arms. The nuts on my rear control arms are welded on. I'm gonna order some other hardware from Morristown, the two bolts that hold the rear struts are rusty too. When replaceing control arms have any of you run into this problem? Can I just use a standard lock nut here? I'd like to replace everything with stainless, any suggestions???

 

Not exactly sure what it is you want to do.

The nuts on the trailing arm that receive the bolts for the control arms are supposed to be welded to the trailing arm. You can still remove the bolts to install your aftermarket arms.

Where do you want to use a standard lock nut?

For the rust...spray some PB Blaster or WD-40 on the bolts/nuts.

 

OK the nut just stays I get it. I still want to use stainless hardware where ever possible

 

Stainless hardware will be cool, but expensive. You will need to provide the thread size and pitch to the place where you are going to order the bolts. Morristown MINI won't have any stainless replacement hardware.

 

Just rememer that Stainless is actually softer (less hardness) than steel. Great for corroision but I have found that it is not a strong as grade 5 and surley not as strong as a grade 8 bolt.

Yes, yes, good point, good point.

Just use anti-seize on the old bolts.

 

For suspension components, use Grade 10.9 or 10.6 (Can't remember exactly). Anything less and you're taking undue risk
