Video #3 in my very limited library of repair vids. This time I am replacing the rear lower control arms on my WJ. Experiencing pronounced left/right lurching when on/off the throttle? It could be your LCAs.
I disconnect the sway bar because it fights me when I try to reposition the axle to unload the tension on the LCA bolts. You can try the job with the sway bar attached ... but it's a lot harder, have fun.
Hope you find this helpful.

How are those Detroit axles? Ive bought brakes n rotors about 2 years ago from them and still good

@Macnificent78_ 2 года назад

Where did you hook the straps up to ?????

@Amarillobymorning777 3 года назад

I made a rocky mistake, I swapped the bolts by accident, the rear is longer than the front one. Jajajajaja, but I did the job. Thanks 🙏🏼.

How are the Detroit Axke arms holding up? Bout to order them up myself

@r2snow 4 года назад

Are the Lower Rear Control Arms the same as the Fronts? We've got a 4.5" lift and need to replace the Rears with an adjustable arm.

@GmanWJ 4 года назад

No, the front and rear LCAs are different.

@mattp9029 4 года назад

What do you mean by "critical to load suspension"? Putting it back under weight before you tightened the bolts?

@GmanWJ 4 года назад

Yes, exactly. You must make sure the vehicle weight is back on the wheels before you tighten everything up. If you don't, your bushings will quickly fail and you will have to repeat this repair.

@robthestud2003 2 года назад

Did you have a tail wag, is that why you changed them? I need to change mine I have the parts already

@GmanWJ 2 года назад

No I had a push/pull when on/off the throttle due to the failed bushings. Worn bushings may cause wag, both upper and lower CAs. Rear upper ball joint is also a suspect for wag

@revolutionday1 3 года назад

Did you have any kind of knocking sound from the rear when that bushing came apart?

@GmanWJ 3 года назад

No knocks for me with this one. Instead, the vehicle would jerk to the side when off/on the throttle.

@GmanWJ 3 года назад

Knocks in the rear, common causes are shocks and the upper ball joint and/or upper control arm.

Hey i have a 2001 jeep grand cherokee i have rear noise skeak grind when turning its a weird noise what could probably be

@GmanWJ 3 года назад

You may need to change fluids in the rear differential. 75w-140 plus Mopar friction modifier if you have limited slip diff or Quadradrive.

@1God1Msg 4 года назад

Good evening, where did you attach the other end of your ratchet strap too? I'm in the process of doing this job myself. Great video 👍🏽. Thanks for sharing

@GmanWJ 3 года назад

Sorry for not replying earlier. I hooked one end to the sway bar and the other end to ... well probably the transfer case skid plate, but I think you could use the "frame rails" on the side. There are a couple of holes there for rock slider mounting points that should work

@TheMainLead Год назад

How are the Detroit axle brand?

@GmanWJ Год назад

Reviews from my Jeeper associates are mixed. I like them fine. I still have them on the front CAs. Anything else there gave me a scary case of the shimmies.

@nebulousJames12345 4 года назад

What is loading the suspension!?!

@GmanWJ 3 года назад

When the vehicle is sitting with wheels on the ground without jacks or jack stands. The suspension is loaded when all of the weight is supported by the springs.

@johnsilva3472 4 года назад

Did you swap the rear sway bar?

@GmanWJ 3 года назад

Yes I have an Addco 684 in there.

@PNW4130 Год назад

@@GmanWJ how ya like it?

@GmanWJ Год назад

@@PNW4130 It was great if you only run on asphalt, corners wonderfully. If you go off-road at all, it is too stiff. So I switched to the smaller Addco 634 which is still very impressive on the highway. Really all you need unless you think your 20 year old WJ is a race car (it is not).
