The bushings on the shock or suspension arms? I've done it twice so far. Maybe my idea of snug is wrong. Should the bolts then be just finger tight when doing the bouncing and driving around the block?

Yes, the stock bushings..and you must release them or car will sit high. That's what those workshop notes are telling you.

I swear I've been following those very directions, but I'll do it once again. This time I won't tighten up the bolts as snug and I'll bounce the car even harder. Hopefully that will release the bushings.

Thanks for your time

Put two big people in the car and bounce it good if you need. Do it again after 500 more miles and it will sit down.

If, and that's if I've tried all your suggestions and it still hasn't setteled, would new bushing like these work? http://www.good-win-racing.com/Mazda-Performance-Part/61-0571.html

Changing bushings not the answer, it just needs to get done right. You will get it done. If needed, drive a few hundred first and try again.

Brian,

As I'm sure you well know, it's a real PITA to tork the bolts when the car is sitting on the ground. That's the way I've been doing it so far. To get more room for leverage, would it still work if the rear of the car was driven up some ramps? That way the suspension is still under load. Or does the car always have to be level to get it right?

Hi Bart,

I just finished pulling out the rear shocks last weekend, following the same install info. No problems were encountered. Starting with the rear wheels in the air, the rear shocks in place, the bolts for the lower shock mount and the two upper links were tightened by hand using only my fingers. The car is then lowered & fully loaded by it's own weight, only then, are the bolts torqued down to spec. The trick to this stuff is getting under a fully weighted car to tighten the bolts. The easiest way for me is to lower all 4 car tires down onto 4 equal sized blocks, 12 inches high, and then get under the car to do the work. Yes, all 4 corners /tires are sitting on these bolcks during the procedure. Safety is the 1st concern, so find the right type of bolcks for the job. I use 12 inch wheel cribs, made by RaceRamps for this type of work. Good luck, you can do this, if I could.

Regards, Pat
