Mopar lift bowed springs - One coil rubs on tie rod

[Roky]

It is a 2.5" spring and I have an adjustable track bar.

Is the axle centered ?

Yes.

 

[Roky]

Yes.

Is the top isolators turned the right way, there’s two nubs on them that go in the holes in the coil housing. I’m late to the party sorry if this has been asked and answered.

Yes, the top isolators are in with the nubs going through. They are the isolators that were installed with the Mopar kit was installed at the dealership. I keep putting them back in the same sides they came out of, are those side specific? ... because the bottom pads/isolators/seats are side specific, and they were installed on the wrong sides by the dealership.

Also, just to catch you up, I began by installing the RK 'correction pads' with the mopar lift springs. That put my passenger side tie rod into the coil spring. So I put the mopar coil pads/seats back in (on the correct sides this time) and ordered the RK springs for 2.5" JLUR diesel... I even got the RK kit that comes with the pads just to make sure I was using the right pads/isolators/seats. It came with the same 'correction pads' ... which pushed the RK coil on the passenger front into the tie rod.

You keep saying tie rod, do you mean sway bar ? The top isolators are the same for both sides……

Yes, the end of the sway bar where it connects to what I call a tie rod. The part circled here... this photo is on driver side...

Just for future reference, swaybar and swaybar endlink are what you're looking at there.

Ok , I read through the thread…. Do you have an angle finder, preferably like the one in the pic…….if so put it on the flat circled in pic, I’d like to see what the caster/pinion angle is showing……..just like the stock track bar pulls the axle to the drivers side when lifted, the fixed lcas pull back on the axle as well. You see mine says just about 90 degrees, that’s 6 degrees of caster, which is where you want to be at 2-3” of lift.

I will do this in the morning and post back what I find. Thanks

Got it, thanks!

Are all the suspension components installed torqued to spec in the below photo?

1. Notice the angle of the sway bar link, this would suggest that your axle has shifted severely to the drivers side of the vehicle!

My post #41 from this thread shows how everything looks with the mopar lift kit coils and pads.

The RK correction pads have the same effect on both the mopar coil springs and the RK 2.5" JLUR diesel springs, the driver side coil ends up further back (away from) the sway bar and the passenger side ends up jammed into the sway bar.

Very odd indeed... If your axle is centered then perhaps;

1. The RK pads are defective.
2. The RK coils are defective, or incorrectly labeled (made for a lighter weight application).

I would think #1 and #2 are unlikely but not impossible.

Just going to throw this in here. My last jeep (2021 Rubi 3.6) I used both correction pads to get my coils straight. This jeep (2022 392, heavier) it took stock pad on passenger and correction pad on driver to get them straight. Lift used on both was Metalcloak 2.5 GC. There have been several people that have had to do this.

That's a really good point, does indicate that the axle may not be adjusted 100%. @rubiconman, can you snap some pics showing how you measured that the axle is indeed centered?
