i got this frame from a guy its a 73cj5 and he did a shackle reversal on the front. i put my new springs on and realized the front axle is pointing downward. the springs didnt come with shims for the front so i was wondering if anyone knows what companys make like 10 degree shims for 1.75" wide springs? when i measured the axle it was like 10 degrees off however i dont have an engine tranny or tcase in yet withh that weight decrease the angle any? any input would be greatly appreciated!! thanks
I think at that point shimming it is not safe on the front axle... You probably need to have the spring perches cut off and re-welded...

should i just cut off the axle perch where the spring meets the axle and get a new one re-welded on? that should fix my problem right?i rather not mess with the frame and have the spring perches re-welded bc its already been done once by the previous owner and i dont want to weaken the frame
yea sorry. the pinion is pointing downward because the guy who had it before me swaped the spring perches so instead of having the shackle in the front of the front springs its in the back of the front springs and with the 4" skyjacker lift springs i put in it that is making the back of the front axle where the pnion is point downward. you think my best bet is to just cut the perch off the axle where the springs sit on and just have it relocated and welded on where the pinion angle is level? im sorry im pretty new at the lifted jeeps ive always been into just restoring old cars and just plain jeeps rather than custom ones
Sounds like the PO didn't get the relative height of the shackle hanger and fixed hanger correct. The perch on the passenger side isn't movable, so there's more to it than cutting and rewelding new perches on.
Sounds like the spring mounting to the frame is where the correction needs to be made.
however i dont have an engine tranny or tcase in yet withh that weight decrease the angle any? any input would be greatly appreciated!! thanks
Yes, that will significantly affect spring compression, main leaf length, and ultimately the pinion angle. Don't make any changes until you get the suspension under load with the approximate running weight of the vehicle. If you change the perches now, you'll just piss yourself off after you install the driveline and everything moves.
However, CSP's point is also perfectly valid and something frequently seen. Check the "engineering" and see if the components are even in the ball park as far as location (spring hanger at the front).
