89 gta trans am restore
ok everyone so im starting my trans am restore abit early im looking to restore components to the front frame (bushings, front suspension, steering components, radiator support) i also wanna put new floor pans from the front toe board to the front of the rear seats. for the rear of the car im also dropping the rear end an putting new axles an a new set of gears instead of the 370s i got now looking for 410 in the rear also looking to replace rear suspension components, for frame tightening i wanna put a really good set of sfc's an a strut tower brace i was wondering what are the best aftermarket companies that will sell these parts for a really good price an also to start things off how hard will it be to drop the front frame what will need to be done thanks for the help in advanced

Re: 89 gta trans am restore
undo all wiring and hoses, take out engine, take off wheel and rent a strut compressor tool, take out struts put jack under k member, take k memeber out. thats basically it, besides taking out bolts and such. pretty easy if you have all the resources

Re: 89 gta trans am restore
You forgot the sway bar, brakes, and the steering. It's actually pretty easy to remove the crossmember. Once the weight of the engine is off of it, disconnect the brake lines from the prop valve, unbolt the struts, sway bar, and steering, then the crossmember-chassis bolts and the entire thing will fall out. No need to remove the struts from the spindles, spindles from the A-arms, or bother to compress the springs. Technically you don't even need to pull the engine unless you want to...

Re: 89 gta trans am restore
The top nut on the struts has to be removed so they can drop down with the crossmember. The strut to spindle bolts are usually torqued down tight, and they're behind the brakes. It's easier to deal with the sub-assemblies after the crossmember is out from under the car. Two clean, lightly torqued nuts, easily accessible from the top of the car are easier, and faster to remove then 4 rusty, super tight, bolts under the car.

Re: 89 gta trans am restore
from my understanding of what drew is saying, you can unbolt the struts from the strut tower cap its one bolt on top per side, and then drop the whole kmember fully assmebled. then the struts are already decompressed so you just have to unbolt them from the arms and such and do what you want with them

Re: 89 gta trans am restore
The springs are compressed between the crossmember and A-arms. Put your jack under the A-arm, jack it up until the arm lifts a bit, and remove the strut nut. When you lower the jack, the spring will decompress. Or just stand back and let er rip. The spring isn't going to go flying, both ends are in pockets.
Going back together, you'll probably need the spring compressor.

Re: 89 gta trans am restore
You can the car back together without a spring compressor two different ways (that I'm familiar with):
1. Buy lowering springs. This is by far the easiest. Just put the spring in place, put a floor jack under the control arm and pump it until you can re-attach the ball joint.
2. Remove lower control arm, set spring in place, and jack entire control arm up until you can get the attachment bolts back in, then the ball joint. This is a huge PITA but if you don't have a spring compressor, or if you have an "external" one like mine, it's an option.

Re: 89 gta trans am restore
Method one is possible even with stock springs. Ive done it this way several times...however using some lowering springs is def easier. With the a-arm dropped down on its pivot point, you might have to give the spring a little help. But at that point, its not compressed THAT much to where its super dangerous.
As always...regardless of how much its compressed, get a chain around it just in case. But Ive never used a compressor on my thirdgen front springs. Just be smart, safe, and use your noggin and its not that bad of a job.

Re: 89 gta trans am restore
Make sure you take care of that $50 compressor! Anti-seize on the threads, make sure its seated properly etc.
I was never able to get a compressor installed to actually do me any good. I know there is a specific compressor for that type of spring set up...and maybe thats why. I was always trying to use readily available compressors. If you get one that fits and works for you though, its DEF a worthy investment! Can never have enough tools!
I have some plans in the works to build in "keepers" for dropping the k-member. Basically a very large bolt that you'd screw up from the bottom, into a welded nut on top of the k-member. But...I dont really make a habit of pulling the k-member (ideally anyway haha), so I can probably just put up with pulling it all apart. My eibach pro springs drop in/out pretty easy.
Good luck!

Re: 89 gta trans am restore
Ehhh... Over on some other forums, I've read a few people have taken their springs to a shop and had them compressed and banded. Then when they're in position, cut the bands with snips. I'd probably look into that before buying a Chinese spring compressor. Using a floor jack and the weight of the car might work, assuming that the spring is soft enough and the car is heavy enough.
