Good thing I bought two of the 21 mm ratchet wrenches. That one nut was so rusted on - when I finally broke it free after numerous impacts then it just kept turning. I couldn't figure out what was going on till I realized the ratchet on the other side was busted. hahaha.
The actual arm was in fine condition in my view but the trailing mount bracket was rusting out - so now I'll spray the bracket with phosphoric acid gel - let it sit overnight and pop in the new part.
I'll paint the bracket with that rust reformer protection paint - it's a tight fit so I don't want too thick of a paint layer.
Pretty exciting to put the new part in tomorrow!!
I had to buy a Deep Socket 21 mm - plus the PB Blaster - tonight.
Meanwhile the fireworks are blasting away - so perfect time to be hammering away on the impact drill.
The mechanic was freaked out by my phosphoric acid treatment that left the lateral arm all white!! haha. He had no idea - or maybe it was just car paint. I had painted white in that area.
Anyway for whatever reason he told me that the "lateral arms" were rotting out - again the one I took out seemed fine BECAUSE of my previous phosphoric acid treatments - along with paint.
Still the bolts were very rusty - obviously - and that is probably what he meant - he can't align the back if the bolts are rusted out. So I sprayed the bolts and nuts down with PB Blaster.
The rubber bushings seemed fine to me - but I suppose they lose their spring power - to have the torque to hold in the back side from lateral movement....
The HARDEST PART of this job is figuring out which way is loosening the nut or bolt - since one side is the opposite of the other - or is it? haha. Since i'm upside and looking backwards - it gets very confusing very fast.
So half the time I'm tightening when I should be loosening, etc.
Like I said - I broke ONE ratchet wrench but once I busted the nuts free then I use the good ratchet wrench left to slowly unscrew the bolt. I think most vids show them hammering out the bolts - but I figure why risk damaging the threads?
I still have no idea what I'm doing but so far no disaster has happened - lets hope my chassis frame holds over night - supporting the car weight. I think those frames are "over-engineered" - so even with some rust - or a lot of rust - them seem to hold up.
