Thunderbird Coils + S10 Bastard Pack Lift

started at 10, just finished at 1:30. An extra hand would have been nice
Heres what i've done:

-Replaced springs with thunderbird springs.

-Added the thunderbird isolator which is necessary b/c the thunderbirdsprings have a wider diameter

-Redrilled hole for the trackbar

-Replaced the shocks

I didn't have coil compressors, but if you disconnect your shocks, sway bar, & trackbar, you won't need them to take the original springs out. I did need them however to put the thunderbird springs on, so I used my ratcheting tie downs. One is enough, you only need about 2" of compression.

Before:



After

i'm doing the rear when the sun comes down. The heat is unbearable, its like 86 degrees out and the humidity makes it worse. I have my s10 leaf springs. Should i keep the s10 overload or not? I don't do any towing, and I have air shocks which can be inflated if I have heavy stuff in the back.

Cherokee at 16 - thanks, i'm having a hard time finding the centercap for one of them. One guy on ebay wants 70bux for it, no thank you

sicma99ot - seems like you live close, i have to wait till this sun gives a little. I'll roast

How do you adjust the steering geometry? My wheel is turned one full revolution to the left when the wheels are centered, so I have a super tight turning radius in one direction, and a crappy one in the other direction

Pull off the pitman arm, center the steering wheel, and put it back on. I just left it for the alignment shop to do.

Adjust the collar on the draglink up by the pitman arm.. Loosen the 2 nuts, and rotate it.. Have some one sit in the jeep and tell you when it centers... DO NOT PULL YOUR PITMAN ARM to center it.

Do you have the year and trim level from the thunderbird donor? My parents are going to be scrapping a 97 v8 tbird soon and I'm got dibs on the springs if they will work.

This is correct. You will also need to adjust the tierod to set the toe after the lift, or take it to the alignment shop. Doing it yourself is easy though, I just finished both on my TJ after installing my new d30 hp today.

thanks XJ cruiser xjfever, and crunch, will do. I was worried for a second. I wan't able to finish the rear, b/c i was looking for air lines all over miami, and no one sells them (for my air shocks). I came back at 6, but while sourcing out tools as well as a non cooperating drill bit, the sun came down, and I don't have lights. Meanwhile, the leaf spring is almost in place, the center pin just has to be fished through the hole on the main leaf. Then I can reassemble the drivers side and move on to the passenger

keepishop, I'm almost positive thats an exact match as a donor thunderbird. I don't quite remember, but it was certainly the same generation thunderbird, and im pretty sure it was the v8.
Note:
I really like the new ride. The springs are much stiffer, and now my cherokee doesn't wallow like a water buffalo. You do feel more of the bumps, but its not harsh. Mind you, this was LA style - the front in the air, and the rear on the floor. I will give an update on ride qualities once the lift is completed

measured at the front, front the center of the hub to the bottom of the flare - 22"

i drove it around and it came right off. My brakes need replacing. I have to find the root of the problem. Violent shaking while braking.

That is usually caused by warped rotors.

lift is done. here are some pictures





ride is a little harsh. But its not a boat anymore so it's a tradeoff.
I'm going to do a write up soon with instructions

Thanks XJFever. I was looking into that. Seems to fit the symptoms perfectly.
