Patience is a virtue

PB Blaster + soak time
PB Blaster + soak time + gentile heat
Kano Kroil + soak time
Kano Kroil + soak time + gentile heat
Automatic Transmission Fluid + Acetone (avoid torch)

Used these on my 74 Triumph, it was mostly win. Never had to get out the BFH. Good 6 point sockets will put you miles ahead as well.

It twists about an 1/8th of a turn and the LCA rises.

I'll also have to source a new bolt to replace the bent one that I'll end up cutting. Hope to find one similar, can't seem to find a direct replacement on rockauto's or oreilly's website. I wouldn't figure there would be anything to critical on that bolt if it's the same diameter, same strength, and fairly the same length.

Call up Tommy at Finishline Performance. He will have all the bolts you new brand new in stock from Mazda. I think the alignment bolts are $6.xx a piece and you need 8 for the full car. The shock bolts are like $3-$4 a piece I believe.

I've got all new alignment bolts. I'm needing the nut and bolt for the bottom of the front shocks. I'll be cutting the bolt that's seized inside the bottom of the shock.

I might try more heat on the rear alignment bolt. I'm hoping I have enough space to get an air-hammer on it. It's passenger rear closest to the fuel pump, the broken part(nut side) is facing the fuel pump. It broke off flush too :(.

Well got the shocks out, sawzall did the trick. I'm still messing with the stuck alignment bolt in the rear, haven't touched the front alignment bolts yet. I may end up taking it to a local shop and have them swap out the fronts and get that stuck one out. A lift and the right tools will probably help out a lot. I'm also tired of thrashing on the damn thing too.

I'm in Ohio, and almost every suspension bolt I've ever messed with has given me issues. I ALWAYS use antiseize when stuff goes back together. One thing I found that helps, aside from the usual PB blaster, heat, and 6 point hex socket, is to put a wrench on the nut or bolt in question, and tap it clockwise like your tightening it. To quote another source.. "give it a sharp rap"...with the biggest hammer possible on the 12mm+ bolts/nuts.

Well my local alignment shop managed to tap out the stuck alignment bolt in about 10 minutes :vash: It might of un-bound on the drive over there or something, lol. Had to take a sawzall to the lower shock bolts,but finally got them out as well.

The Xidas are simple put, amazing. It's amazing how comfortable they are while being so stiff. It's amazing how neutral and easy to control the car at the limit. It's amazing how bumps and transitions don't unsettle the car at all.

Did an autox yesterday with them, 1st and 2nd in STR out of 7 people running, 8th and 15th in PAX out of 70, with a pretty strong feild(a few national champs). My co-driver always demonstrates how fast a car is really suppose to go and I have a lot to learn with the new setup, but I'm insanely happy with it :party:
