need shock help - hendricks rubber block

this is on my dump truck i have the hendricks rubber block and i replaced the blocks a few years ago factory and now nee some good shock (i think) thats my problem..anyway here is what the truck is doing at 55/60 it has a bad bounce in the back the walking beam bushing look to be in good shape gonna replace them next year, but the shocks has holes in them and look to be factory aswell 1997 truck...the bed and all the stuff in the pass. seat bounce out in the floor when the bounce start if i put my foot on the clutch the bounce is still there..i had a u joint replaced last week and all others checked and are good...the carrier bearing was checked also was good,i can see in my glass that the tire looks to be bouceing back and forth but could just be the road..what do you all think it could be???? im going to replace the shocks either way but thought i would ask what else maybe the problem..its not the tires ,i have moved them around and changed rims from time to time so its not that..thanks mike

 

yea i know its going to bounce some but man this thing is just bad...i picked up my new shocks today will put them on this weekend and hope it will calme it down some.....also going to replace 1 of the tq rod bushing at the same time so thats gotta help as well..the 1 on the chassis on the back axle is going bad so while im working on it i might aswell get it done to..thanks mike

 

well got the new shocks on and they got to help the shock i took off where the factory shocks (hendricks) and you could push them in and they stay or pull them out and they stay lol...but now im trying to get a tq rod arm bushing in and it is killing me it went half way in a stopped so i got to get it (the rod) off the truck and to a shop.. i tried heating it to exp. the metal but it doesnt seem to want to work with me...so ill keep you posted ...oh the shocks had holes in them so i sure the oil was gone lol mike
