40 series cruiser lean was discussed. Here’s some additional information as promised.
First Insure the shackle bushings are lubed and the shackle bolts aren’t over tight and binding the shackle from movement.
Emu marks their leaf springs with a + or - or 0 at the perch end depending on the spring rate. All leaf springs will be labeled with either a “+”, “0”, or “-“ which signifies a tolerance of up to 3mm. “0” is exact, “+” is slightly above up to 3mm, “-“ is slightly below up to 3mm. To avoid lean typically you install them + front left, - front right, + rear left and - rear right. You may have to swap a pack left for right depending on your situation.
All or most FJ-40's lean to the left a bit. Toyota has a bulletin about it. "Toyota Service Bulletin; Volume 5; Reference, Body; Number 10; November 14, 1976; Model FJ; Title, Body Slant" is the bulletin. It says to measure and find the "high corner"
(right rear, generally) and to install the listed Toyota Factory Slant Correction Plate. Yes, there is (or was...) such a beast. The part number is 48475-60010 and the caption for it reads: "Plate, Spacer". You will also need two longer U-bolts, part number 90118-14107, that are 175mm (or 6 7/8") long. Job time is rated at eight-tenths (8/10) of an hour and is reimbursible within the provisions of the Warranty Manual for dealers (Not that the warranty matters anymore...). Basically, you pull the u-bolts on the right rear, slip the spacer plate between the spring and the axle, install the new, longer u-bolts and tighten to stock spec. How does it work putting the plate on the high side, you may ask?
Well, it isn't all that thick, but the length is key. Tightening a flat plate against the leaf will flatten or pre-load it a bit and lower that corner, leveling the vehicle.
