Do u need to do the rear lower if u do frot lower and rear upper also?

 

No, you can do them all independently. If you're not going to do all 8 arms at once, start with front lowers and then rear uppers.

 

Why front lowers and rear uppers? Why not lowers front and rear?

 

I doing teraflex front lower and rear upper

 

Now you got it

 

And I'll have someone adjust the caster so it's right cuz I'm not positive how to do it.

 

I run Teraflex front LCAs and UCAs, I'm very happy with them.

 

Ok I'm gonna do front lower and rear upper TF. Did u install yourself

 

Both are front. I installed them with jks track bars (fr/r) and with an old man emu suspension lift. Did it all myself...very easy!

 

check the write-ups or wayalife.com. It is fairly easy. TF also has good instructions.

When you get ready to adjust the rear, most instructions have you adjust the pinion angle for double cardin style joints. If you have the factory drive shaft do not follow such instructions! With factory shafts split the angle between the front joint (on the rear drive shaft) and the rear joint. Double cardan style shafts require the pinion to be in line with the rear joint.

Have you looked at your rear coils springs? They may be very close to your track bar, if not hitting it. You might need some spring wedges. Watch the bow in the coils when you are adjusting your rear upper control arms.
