Hi. On my 2001 DRV3500 5.9L I replaced the front lower ball joints w/Moog parts about 10,000 mi. back. For a few different reasons I believe a vibration I have only during acceleration at mid to higher speeds is related to my control arms. Assuming the lower ball joints are OK would anyone know if other than the upper ball joints there are bushings also that should be looked at connected to the control arm. My repair books don't seem to show bushings.
Thanks

 

First start with the free stuff by swapping your tires front to back and see if the vibration changes. You want to eliminate the tire as a possibility before you start changing parts. But to answer your question, the lower and upper control arms have a bushing at each bolt holding it on.

 

Thanks already did that and a whole lot more.
With foot off the gas ride is smooth at any speed. Started looking into this in post titled "shimmey revisited". What I thought was 1 problem was several and I'm down to the last symptom. Thanks I'm gonna hit those bushings.
