Rear Upper and Lower Control Arm Installation

[MajiJeepTJ]

Hi, I am going to install the rear upper and lower control arms in the street (no driveway), so my question is how do I do it. I understand it is pretty straight forward. It is all stock suspension and stock control arms but what is the best way to do it, jack up the Jeep, leave it on the floor, ??? I watched a bunch of videos and there were many different techniques so I just wanted to know the safest and most efficient way possible. Thank you for your help.

Just remove one at a time. lift it slightly if you want to. It's been years since I tried to crawl under a stock Jeep.

If you want to be extra safe toss a few stands under the frame. You should have no issue replacing the OEM arms if you do it one at a time.

Do it at ride height on level ground. Put it in 4lo, roll forward a little then set the park brake and leave it in gear. Then take the arms off and on one at a time.

I don't know if you have the parts already or not but your best bet is to get under there and make sure you can get every bolt loose before you take any of it apart. Sometimes their kinda rusted into place which makes it harder.

Start with the passenger side upper. That will be the hardest due to working around and over the muffler. I had to drive mine up on ramps to get enough room for a breaker bar on that one, and my TJ is lifted.

One tool to make sure you have is an alignment bar https://www.sears.com/craftsman-1-4-x-12-in-line-up-tool/p-A038484026 I know some will say a big screwdriver works but proper tools make life easier.

Also do not torque anything up until you have all the arms installed and you can bounce the Jeep a couple times to make sure the bushings are neutral first. Clevites last longer when not preloaded at ride height.

Thank you, well I will do my best and here come bloody knuckles and some choice phrases I tell my six year old not to repeat.

Yep, or if you used to know a jeweler that trusted you with his ring sizing tool, that works too. Not that I would know because I would never use my friends ring sizing tool for something like that...
