I hear a knocking sound and a move to the right side from my back when I slow down sometimes, I put on joints on the right rear and I need to put some on the left rear could this be because I nave to put the u joints on the left rear

U-joints & related parts. typically fail at the same time. especially. if they are original?? you should inspect ALL joints for play!!

Bushings would be more in line with side-to-side movement. U-Joints on the other hand would click or make noise when the load shifts from acceleration to deceleration on the driveline parts.
One test would be to go from neutral to either drive or reverse and see if you get some form of 'clunk' originating in the rear area. Probably be the half-shaft u-joints but could also be the drive shaft units.

Best guess on limited info.

Sounds like U-joints, but inspect the bearing while you're in there for play. All of it tends to go bad around the same time.

Get Spicer forged joints

all of your replies are what I thought it was I had some wheel bearings put on then the u joints so to be on the safe side I am going to replace whatever is left thanks again

drilled and slotted rotors well worth the couple xtra bucks, I bought a complete set from summit and had the local shop do the drilling and install, run out was not a issue as I made clear to the tech of the issue and instructed them to lightly sand both mating surfaces, as you said this is a must do... also that parking brake issue its a pita theres many threads on that topic alone and to do that job I advise a full weekend and a full cooler of cold ones. mind I also replaced all 4 tires and 4 calipers and semi metallic pads, braking distance is apx 3/4 the distance it was on stock, we all tend to ignore the brake pedal because we spend so much time on the go pedal but when u need it that stop pedal comes in handy
