Are there any good writeups for swapping springs? I just picked up a set of Rubicon springs and shocks to install into my X Unlimited. I assume this should be pretty easy, but would like some instructions before tackling it.
- lift Jeep by frame and put on jackstands, (if you can't get it high, take your wheels off)
- put a jack under the axle and raise it till it just supports the weight of the axle.
- remove bolts for sway bar (lower) and lower shock bolts
- slowly lower the jack holding up the axle. It will drop low enough that the springs should fall out.
If you have a spring compressor, its a bonus - ESPECIALLY for tall springs. If you have an auto, you might have to remove the tranny skid plate or else it will catch the front drive shaft, preventing it from lowering far enough (again, spring compressor is nice). I was able to put OME 4dr HD coils in mine without removing the skid plate or the track bar. I used a compressor though, just because I had it. Not sure if I needed it. You can rent them REALLY cheap.
Total job was just under 2 hours for all 4 springs with the right tools. My coils replaced a BB, so I already had shocks on.
'07 JK 2dr Sahara - auto w/ 4.10's and rear locker. 2" OME HD coil lift, BDS shocks, and 1" body-lift. 34" Hankook RT09 MT's on 16" AEV Bridgers. ARB diff covers, Warn bumpers, Warn 9K winch, a couple Hella lights ...and a WORTHLESS AirRaid CAI.
Before you make the switch, take a look at the tags on the new springs and your current springs. If the last 2 numbers on the new springs are not higher numbers than your current springs, you are wasting your time. The front springs should be 2 different numbers with the lower number going on the driver's side.
Rubicon springs are not necessarily stiffer. An unlimited with tow package has the stiffest rated springs. The is a great write up somewhere on JK Owners.
I just finished swapping one front spring, took me about 20 minutes. I went from 13's to 16's and unfortunately it only gave me about 1/2" of lift (I should have done better research). Both front springs had the same numbers. I'm only putting on 33's so I don't need much lift anyway, plus I am planning to trim the bumper tomorrow and maybe the fenders if I have time.
I'm working from home today so I'll do the other springs throughout the day and throw up some pics when I'm done.
