Default where to get a transverse leaf spring compressor (for rear spring on 93 vert)

Just curious...is this a regular 'loaner-type' tool from autozone or is this something special?

What did you use?

Floor jack & wood block.

Vehicle on jack stands.

Raise one spring end to releive pressure on the spring hangar bolt. Remove bolt.

Ditto for side 2.

Loosen 4 center clamp bolts.

Remove bolts from 1 side & collect the shims located between top of spring & mount. Keep them separate.

Remove remaining 2 bolts, collect the shims.

Respectfully disagree.

The spring hangs from the carrier. Raising the carrier places a heavier load on the spring.

Yes, put the rear of the car (frame supported)on jack stangs, the lift one end on the spring to relieve tension with the floor jack. Loosen the nut (after taking the cotter pin out) and when the floor jack is let down the end of the spring will be loose too.

Thats the way I've done it every time I've had to do something with the spring or knuckle that required the spring bolts to come out.

I also agree with Churchkey, however with the vehicle on jackstands I used a 2X8 (about the width of the car) placed directly under the spring. Then, I placed 2 20 TON bottle jacks on top of the board and raised the spring at each end slightly. With pressure relieved I removed the spring bolt nut. Then lowered springs slowly. As the springs dearched the bottle jacks will slide, but this must be done slowly and carefully. I removed my springs to install the Vansteel coilover kit.

The bottle jacks allowed me to do this project with the car raised high enough that the springs can be removed from the car. I used my harbor freight 20 TON press bottle jack and an air/hydraulic one I also purchased from Harbor Freight.

Good luck with your project!

OK..so I dont need any special tools to do this. ?


What about reinstalling the spring? do i need a tool there?

btw all this work is to replace worn out ozone rotted batwing carrier bushings. I need to lower & remove the diff to do so .

Since I was putting it back together by myself I bolted the center section back to the carrier while it was supported by a jack (forget which one I used, probably the floor jack) then used the block of wood and jack to get the bolt on a couple threads, then did the other side.
Then run the nut up to the desired position. voila - no reall muss, fuss or other issues

I'm sure the 20 ton jacks worked well. Lighter, smaller, less expensive 1 ton bottle jacks or a small floor jack with a wood block will work also and be easier to handle and be less expensive. I think the 20 ton jacks are used for lifting houses.
