Tips for B5 A4 suspension bolts *seized*
« on: May 17, 14, 17:27 »
Last A4 I owned the bolts were not this seized.  I've tired heat, banging on them, a few different penetrating oils and this one bolt is still stuck solid.  I'm almost at the point where I want to take it somewhere to have them remove all four bitch bolts and put new ones in before I attempt to install my suspension again.

you dont have to take the pinch bolts out to do the coils, i am guessing you are doing control arms aswell

Aside from that, have you tried a large breaker bar for leverage? I've got a adjustable 2-4 foot 3/4" one That gets used for special occasions

I have to deal with this problem quite often, and typically have to sacrifice upper arm outer balljoints and boots (basically new arms altogether) and alternate between heat and cool down with penetrating oil, then working the bolt both directions til its loose enough to start working it out with an impact. Never been stuck yet or had to drill one out, but bolts are supposed to be replaced so get new ones no matter what they look like after they are removed!

If you are sick of working on it I can take it in and remove them but it might cost a new set of upper arms.

I managed to get one out, and replaced it with a new one.  I'll work on the other one this weekend.  The outer boots are going to be fubar but I have new ones so it's not a huge deal.  I'm thinking a nice 10lb sledge might loosen it....

Thanks for the tips Jeff
