Icon leaf clunking sound

[Doc_RR]

Just installed Icon leaf springs, but kept it at level 1. Raised the rear almost 4 inches (40 1/2 to 44 1/8). Definitely stiffer, but I am sure it will settle. I have an issue though….I know am getting a clunking sound over aggressive speed bumps. Everything torqued to spec (189/81/145 ft-lbs).

1) possibly the springs hitting the exhaust, but seems to have plenty of clearance and no marks on the exhaust
2) I noticed my wheels will shift inside-out with some lash and clunking sound when I aggressively rocking them with my hands and knees, with the truck lifted.

What the hell is going on? No way the axle nut all of a sudden is loose, right??

Also, installed SDi E-cliks, which are awesome. I don’t need to zero out the shocks, right?

Did you torque everything on the ground? (Wheels on, suspension loaded)

Yes, torqued while on the ground, after jumping on the tailgate. Then took it for a spin and rechecked. All based on icons directions

I just reviewed the torque specs from Icon, and they are different from a PDF I found for a 18 Raptor

Front bolt: 181 ft-lbs(icon) vs 258 (Ford)
Shackle bolts: 89 vs 173
U-bolts: 145 vs 98

I emailed Off-road Alliance, but what do you guys/gals think?

had it too after my install, eventually went away, thought it was exhaust too but the only marks are from me scraping it when putting it on
