Rear spring installation help ?
Time for a few safety warnings.
- Jack's are for lifting and lowering the car or parts of the car. Jack's don't safely support anything. That's what jack stands are for. Get at least 2 for this job.
- Floor jacks and trolley jacks operate on hard floors. That type of jack must roll freely or the jack will pull or push the load horizontally in addition to lifting it. That's a good way to bend frame parts or pull the thing off proper stands and do major damage.
- At a minimum you need a sheet of 3/4 plywood "floor" to work in that location. Cut a couple 24 inch squares from the end to go under the jack stands, use the remaining 2'×6' piece under the floor jack. If the plywood buckles under the wheels of the floor jack (with the weight of the car on it) you might need to move to more stable ground or spread a thick layer of gravel on the ground where you're working.
i also noticed that the cups or not mounted into the spring, they look loose.. this is not helping you... remove and install.
see post 12 in the link i posted earlier with my springs..
the cup is pressed into spring first..





From top to bottom: TRW 330#, Hyperco (Ridetech) 300#, Eaton stock replacement 9-leaf.
With stock TA spring bolts the ride height was ridiculous with all three of these springs. I ended up with 8” bolts and the Vansteel 340# rear composite and QA1 coilovers up front to achieve an acceptable ride height.
Also be very careful the front two spring hold down bolts are the correct length. To short and they won't have enough threads to hold, to long and you will destroy your rear end.
I had had a similar situation last month. Good luck.
Just finished reinstalling mine….my fit was off too but swivelled the bolt as described above. My spring, which I think is aftermarket was way too high. Took it to a spring shop and had them de-arch 2.5 inches from it. Perfect ride height now. I used the 10 inch bolts which will allow for lots of adjustment. Like others have said….safety first….if this spring let’s go you can get hurt real bad….
