Heat, heat, and heat. That area is a rust-trap for the bolt threads that point up. I soaked them in so much PB Blaster, and one of them still broke. It had probably been fused for years.

At least you'll have good practice drilling....

Actually, stock up on quality left-hand drill bits now.
Antique car guys all swear by a 1 to 1 mixture of ATF and acetone to break rusted bolts loose.
The consensus is it works far better than PB Blaster.
Also, the crayon method has good reviews as well.

On reflection, does anyone know the torque spec. for the inboard swaybar clamps off the top of their head. It looks like I had them too tight.

EDIT: Oh yeah... Should be 37 ft-lb on the shells, and 17 ft-lb on the end links. I bet I had 59 ugga-duggas on those.
Back when dinosaurs roamed the earth, front sway bar bushings were tightened until the rubber squished out just even with the washers top and bottom.
But, I'm an old fart, so your mileage may vary.

those books are far too pricey for me, I already have the .pdf cd version which is functional but you have to search it with keywords, the .pdf hacked ones are not hyperlinked, so when it tells you see "setting the guide pin" or something you have to go find it and it's like 15,000 pages so.. lol.
then I have Chilton hardback which was probably a library book at some point, not as in depth but it comes in handy sometimes.

Speaking of front end work. Got one new lower control arm on the 2012 this afternoon.

I really need to do my fronts, just haven't shelled out the $1k in parts to get it done.
Did the rears about a month a half ago and it made a big difference as one air bag had developed a very slow leak.

I rented two spring kits from AutoZone, for a total of four clamps, but only used three on the coil. That seemed much more controllable than just two.

I wish they still rented the big single-piece tool. When I did my Armada coils it was so much easier dealing with a single tool that didn't shift around.

I also just want to reiterate how stupid GM truck upper strut mount design, with the shock shaft nut recessed down inside the mount so far that it's a huge PITA to screw it off/on. Why are people allowed to be that dumb?

Today I replaced the tie rods, which had given up after just under 12,000 miles. I also re-measured my axles with my new, inexpensive wheel alignment device. This has significantly improved my truck's handling. It now steers as lightly as a Mazda MX-5 and as precisely as a McLaren... :Big Laugh:


Love your toys. Jealous. Thanks for sharing.
