What did you do for your ZHP/ BMW / MINI today? #2

Other pipe is the stock resonator.

I have stock headers.

That's quite the list. Good stuff!

Thanks. I feel bad, all my attention goes to the ZHP. Finally I decided it was the Mini's turn !

All this in 1 day? You go boy!

Yeah, all in one day. My Indy is very quick. I just noticed one thing after the repairs: the "check your gas cap" warning goes on and off. I will go back if it continues.

Working on the upper/lower balljoints/bushings on the trailing arm. Got one ball joint out and new one in without too much drama. Was working on the lower bushing, but it's apparently too seized in there and I managed to shear the fully threaded bolt in the Koch toolset.

For reference, it appears to be a M12x1.75x140mm bolt made of stainless steel (A2-70). I ordered a Class 10.9 steel bolt as a replacement which should be a bit stronger. Hopefully that works.

grease the crap out of the new bolt and put some heat on the flange that the ball joint is in....

I just purchased new bolts and nuts at 10.8 for the exhaust. Will those be strong enough for weather and heat?

Yeah I did grease the crap out of the bolt, but I guess I'll have to get some heat there too. Was hoping to avoid that with the limited clearance and maneuverability under there

I would go stainless for exhaust bolts and nuts if possible

wowzers. that is seized! i removed all of those ball joints and every bushing in the rear end with that tool, no issues. what were you pressing with on the other side? also, i sprayed both outer bushing/ball joint casings with PB Blaster (the old units), before pressing them out with the koch tool.

Well I was just using the fittings mentioned on the instruction sheet, and was cranking against that assembly with a lot of force before the bolt ended up shearing. Did spray it in PB blaster overnight. Might try some more (or just nut up and heat it with a torch).

odd. here's how i did it - the part circled in red is from a universal bearing driver set i had - it matched the OD of the old bushing:

Your's looks a good bit different than the one I'm using. This is what I'm using:

Though now that I look closer, seems like the bolts were already replaced with generics once before (I borrowed the toolset from someone on m3forum)
