New 2.5 BDS lift one side higher

Good morning, I finish the installation of a new BDS 2.5 inches lift kit on my 78 CJ7 and add new tires and wheels as well. I notice the jeep looks higher on the "passenger" side, I measure the height at the body mounts and I notice is about 1 inch difference, I also measure the angle of the rear shackles and they are different.
Has anyone had this issue? How can I solve it.

Thanks for your help

Make sure your shackle and hanger bolts aren't torqued too tight.

If that's not it, you could swap springs, left to right. If it leans the other way, the springs are arced differently, and should be returned.

If you swap the springs left to right and it still leans in the same direction, then your frame may be tweaked. Search the term "Jeep Lean" for more info.

Mine was like that for a while.. But then leveled out.. These days if I get a lean it's the spring bushings.. Worn out. Usually about once a year.

Thanks, I am going to do what Matt1981 is reccomending, hopefully that will work, I hope is not the frame.

Here are some pictures of the jeep, before and after.

I'm familiar with the jeep lean, but throwing this out there...

If OP is 1 inch high on driver side (I'm assuming empty of passengers), what would it look like with the driver behind the wheel?

Just thinking out loud

The OPs rig looks to be higher on the passenger side, not the drivers, but perhaps it's the pic angle. Dunno

Matt1981 you are correct, is higher on the passenger, when I added this post I forgot which side was higher.

I hate to tell you this. Your CJ has the classic "Jeep Lean". I hope that's not what it is.

It was caused by a factory defect in the frames. Some claim they got twisted in shipping, but who knows.

Anyway they all leaned the same way as yours does. AMC's fix was to place a shim at the passenger rear spring perch. Apparently this flexed the suspension enough to level the body out.

Let us know what you find out when you flip-flop the springs.

Matt the shim actually lowers the spring itself as the springs are below the axle. Jeep CJ frames are not very sturdy, broken spring and shackle hangers are common. A couple of old Jeep quotes; If the Jeep is not leaking gear oil from the transmission/transfer case area one of them is probably empty and If it's leaning it's still stock.
I had a CJ6 (1956) one frame rail was 1" forward of the other, it was stock, never wrecked.

Mike,

Yes, the shim does lower the passenger spring. Wouldn't that compress the passenger side slightly and flex the driver's side, thereby leveling the body?

Also, I don't think all CJ frames came this way, and not all CJs inherently lean like that over time, as your quote implies. It's obvious on the frames that were affected. There are write-ups in which guys have cut, re-squared, and welded their frames straight, instead of using the shim.

Anyway, I hope the OP finds out it's something else. If he's anything like me, the lean is bugging the crap out of him.

Matt
