New member 2022 Raptor rear suspension problem

[GCATX]

Didn’t the issue only occur after you installed the aftermarket rear suspension components? I’d so, I’d start there. Did the instructions say how the components should be torqued? Such as with the vehicle off the ground, or with the weight of the vehicle on the suspension?

I bet this is the answer.

I hope this is the answer, that would be awesome. I can’t imagine what else could be wrong. What does the rear suspension feel like when it is sitting there parked, when the push down on the bumper or bounce on it. Does it move up and down normally. What a learning experience, real fun. Thanks for the help.

Did you torque all the fasteners with the tires off the ground?

This is from the Workshop Manual. I would guess RPG is the same.

NOTICE: Tighten the suspension bushing fasteners with the suspension raised by a jack to curb height or with the weight of the vehicle resting on the wheels and tires. Otherwise, damage to the bushings may occur.

Would depend on the bushing type. If they are heims or poly it shouldn’t matter. Pretty sure the oem bushings are vulcanized? to the bushing housing so on them it does matter.

Yes, I did torque with the truck in the air and tires off. The RPG kit came with spherical bearings that I pressed in.

Same with the track bar?

 

[semaj]

Yes. Same as the track bar.

Yes. Same as the track bar.

It sounds like the suspension is bound up. I would recommend loosening all of the fasteners with the weight of the truck on the suspension and then re-torque as follows:

Lower arms, upper arms, and panhard bar are all the same spec:
Torque: 173 lb.ft

Ok, awesome. That’s what I will do for sure. Thanks so much for the torque info and the help. I will let you know what happens. Thanks

Upper control arms, eibach springs 2.2“ and tie rod kit. Still need to do the Gen 3 recalibration, tried on my forscan but different procedure then the Gen 2 and I can’t figure it out.
