So... was I supposed to remove the coil spring isolators when I installed the lift? I left in the fronts and rears to diminish any potential banging. All four springs are evenly seated up top, with no apparent deflection of the isolators.

 

as you can see my rears are curved. my front springs are not. isn't this due to the slight rotation of the axle for the increase angle of the driveshaft?

 

Yes, and in both of those photos the coils are bowed.

 

No leave the rubber isolators in. I am talking about he axle end.

 

how do i fix the rear coils then? do they need to be rotated?

 

In an ideal world yes cut them off and rotate them. Some people will not do that so they make coil wedges as well. I do not know it metalcloak makes them but i know rock krawler does.

 

Did rear control arms come with your lift? It looks like that axle has been moved back quite a bit

 

yes the rear control arms did come with the kit. its the metalcloak 3.5 ARB kit. maybe they need to be adjusted?

 

Like Mertz said. Cut off the old perches,rotate them back to the top of the axle, and weld them back on. If welding is not something you can do JKS makes a new coil perch that bolts on and is adjustable.

 

A couple of different conversations here. With regards to my front passenger spring... the lowers are the same length, the axle is squared/centered, caster is 4.5° , springs are seated appropriately top and bottom -can I assume at this point that a replacement spring is necessary? If so, do both fronts need to be replaced as a set (between 9-10K miles since install)?
