Installing 4" SkyJackerlift on Saturday!!!

Installing 4\" SkyJackerlift on Saturday!!!

O.K. I am psyched about putting my lift on but wanted to solicit anyones' input on any problems you might have encountered while doing it. My particular vehicle is a 90 Jimmy. I have purchased the 4" skyjacker lift with springs all the way around. I have my floor jacks and all my jack stands and my compresser and impact wrench and ratchet ready to go. Any tips on the ease of the process? It appears to me to be a straight forward job. How long did it take all of you? I've got a team of buddies willing to help me out.

Get some PB Nutblaster from the parts store (I know Napa has it :-) ) and spray everything down the night before so it has a chance to soak overnight.
Man! I can't wait until I can get my lift! Tell me how it rides, would ya?

15/16ths, deep well, 1/2-inch drive socket. Makes the job of removing and re-installing the nuts on the u-bolts go WAY faster.

And yes, air tools make the job go MUCH faster.

Also pick up some white lithium grease. Grease the heck out of the urethane bushings before installing them into the springs. It will keep them from squeaking.

Torches to heat parts up when trying to remove them. Such parts would be the bolts that hold the springs to the mounts, u-bolts, steering arm, etc.

BFH is a short term for Big F---ing Hammer, for the aid of removing the steering arm. Trust me, you will need this hammer!!!

Torches: because sometimes you will need to heat things up to help "persuade" them loose.
BFH: Big F@#$ing Hammer ... self explanatory ... commonly used in conjunction with the torch.

Unless you're on the coast of Carolina I would bet it will all come apart ok. Just start soaking things down today to give the Blaster a chance to soak in. Beating on the steering arm will usually get it off, but some have needed to torch them. I did the same set up-4" Skyjacker Softride springs all around and I love it. It rides way better than stock. Things I added after the fact: 1.5" block to the rear, 1" x-fer case drop, & extended SS brake lines. Good luck.

I have the exact same lift and truck. The only problems I encountered were: the u-bolts even with PB Blaster, didn't want to budge. BARK BARK, I knew I bought that tool for something. Got out the air saw, with a new pack of blades, and cut those mothers off. had them all off in about 1 hour, with beer brakes and all that jazz. You have new bolts anyway.
#2, as the steering arm. Soak that baby Right now and as many times as you can remember between now nad the install. Make sure you hit down on the arm not up........
Dont hit the threads..............

#3. I still had some vibration problems after the lift. I lowered the T-case. It got alot better but still poor. SO I added some washers in with the T-case spacers, (THANX STEVE) and that pretty much fixed that.

#4 The driveshaft was a little too short after the install. I had to measure for proper length and have a new one made.

#5 and the biggest pissing match was removing the shackles on the rear. Those mothers were so rusted the sleeves actually started mating with the bolts. I had to crusify those bastards to get them out. MORE PB BLASTER. Not even the 400lb Impact could budge them.

#6. Cleaning up for the beer run. I forgot to get enuff beer for the entire install. So I had to drive the wifes car.

#7. A VERY GOOD HINT HERE..... Make sure you have the shackel/spring eye bolts all installed before you attach the axle housing to the leaf springs. They are a bitch to contort to get the holes to line up with all that weight attached.

#8. Last but not least, get some help it will go ALOT easier.

OOPS, one more, The forward attachemnt for the rear leaf springs...... The mount is riveted to the frame and the nuts are in between the frame and the mount. Very much of a pain the ARSE for me to get a tool in there to hold it still while loosening the bolts. BABY TURNS.

PB BLAST EVERYTHING&gt;&gt;&gt;&gt; Good Luck man.

Will work for beer, parts and tools.
