Jeep Patriot Rear Lower Control Arm replacement & Bushing Preload

In this video, I show how I replaced the Rear Lower Control Arms and a procedure to preload the bushings before tightening the mounting bolts and setting the torque.
I also added graphics to show how the rear sway bar links (bolt style end links) had to be evenly compressed and tightened to avoid over tightening them.

If there's enough room I would snug all nuts after the arm is installed, put the wheel back on, lower it and the tighten the nuts to specs. That pre-load would be perfect. I will try this when I install both rear lower arms on a compass this week.

Hello my jeep patriot 2.4 4x4 latitude sags in the back suspension and no ride highth. I got upper and lower arms now I'm thinking of rear sub frame

Many people had the front sub frame and/or the rear sub frame replaced because of (rust) structural damage. There was a Jeep service bulletin (23-007-17 REV. B) and a 10 year warranty added to replace the sub frames.

@MTLCARGUY oh ok thank you ,yai forgot that few yrs ago when they had one of the recalls Chrysler said I had a warranty on the rear subframe to replace for wear not for sagging

Can i replace just the bushings if the main parts are still in good control?

Probably, if the parts are available, but you need a good press and the proper tools. Check online with Rockauto , Advance Auto Parts or Amazon.

I just installed the upper and lower control arms as well as the dog bones , the package contained two left handed lower control arms , I was lucky that my sway bar attaches directly to the control arm and not the welded bracket on the control arm. Is it a problem if all the bolts are tightened and the preload was not done ? , yet the frame to wheel measurement came out to be the same before the installation.

Lifting the trailing arm to the initial measurement sets the arms to angles equivalent to the position of the vehicle when it is parked on an even ground. If the bushing(s) is/are tightened when the coil spring is fully extended with the trailing arm lowered, the bushings will be twisted later when the weight of the vehicle will be applied on the wheel in normal parking condition. So, the rubber bushing(s) will have to endure more axial torsion than what it is made for and it/they will not last very long. The bushing(s) can be readjusted to get rid of the axial torsion by loosening and tightening the bolt(s) to specs when the vehicle is normally parked, but, the space to work under the vehicle is very tight and you have to be quite handy to do it that way. Note: A spherical bearing side can be tightened to specs without load or preload conditions.
