How do I determine my body lift?

I just bought a '87 4.2 Liter YJ that has a raft of extras, 33 x 12.5 tires with 1 1/2" or 2" spacers, brushgard with driving lights, custom bumpers with a swing out rear with jack and luggage mount, Kenwood AM/FM/CD radio, hard top, full doors, and it is lifted. The only problem I have is that 33's rub the springs when I turn hard, which isn't a big deal.
My question is - how can I figure how much lift do I have?
Thanks - Ted

post pictures of it. good pics from the side and rear.

there is a bolt on each knuckle up front. it is your steering stop. if you back it out a few turns, you can get to where it hits the steering stop before the tires touch the springs. take a look

Hi Poke - Thanks for the information on the steering stops. I will check them out and take some pictures and post them tomorrow as it is raining here today.

If the tires were installed on OEM rims, you most likely have the wrong backspacing. By limiting your turn radius with the adjustment Poke suggested, you will be able to stop this but you'll end up with a larger turn radius.

A body lift won't move the tire away from the spring.

Often the spring manufactures with paint a part number on the top of the leaf spring. You may need to clean it some or brush the dust off of it to clearly see the number.

Google that number & you may find that leaf to be part of a lift kit.

Check the shackles too to see if they are lift shackles.

Stock shackles are 4" from bolt hole to bolt hole. 1" lift shackles will be 6" between holes. 1/2" lift shackles would be 5" between holes etc etc.
