my 99 jeep grand cherokee laredo is having probs in the rear end .
when i let off the gas at speed the rear seams to get loose and tight agian when i get back on the gas.So i think the control arm bushings are going bad,does this sound right to any of you? then can i just replace the bushings or do i need to get new control arms?

Your rear upper control arm is shaped like an "A" with the appex mounted to the differential housing bracket with a type of balljoint. The two "legs" are attached in the front in the conventional manner. The "Balljoint" can be serviced by separating it from the control arm with a pickle fork after removing the nut. It can then be unbolted from the axle housing and replaced.

i think i may have called it the wrong thin my jeeps rear axle is connected to the unibody by to long arms it looks the arms are like 10-12 inchs long and like an inch mide and mabey 2 inchs tall with a bushing in each end one oin the body and one on the axle so can i replace just the bushings or do i need the new arms? theres ball joints on the rear too?

You have two regular lower control arms, and one upper arm shaped like an "A".

your jeep has a three link rear suspension consisting of an upper A-arm and two lower control arms but i don't really understand the problem your having,could you explain any better?

edit: sorry,ol'blue beat me to it

the 2 lower control arms are they supposed to twist cause i can twist them in their mounts so thats what lead me to them as my problum i thought the bushings were bad

no,you should not be able to twist them

They are old, and being rubber they're probably cracked and will have some play. The upper joint being metal will wear out. While laying under the jeep with the tires blocked and e. brake on, have someone you trust switch the shifter from drive to reverse, to drive, to reverse etc. while watching the control arm attachment points to see where the movement is occurring.
