i have the oem shocks on my f 150 and i was wondering if that could be causing a slight vibraton in the rear. my truck has 130,000 miles on it and are rancho rs5000 a good shock? could bad shocks cause a slight vibration

 

No, a bad shock wouldnt cause a bad vibration.
Check your wheels to see if a wheel weight came off, also maybe check the driveshaft to see if a weight came off.

 

Bobby is right can't cause vibration, but I have the rancho's and I like them.
Check your wheel balance first.

 

Describe the vibration. Is it only when turning? Say like accelerating from a light and turning at the same time?

It sounds like limited slip chatter.

when i speed up to 40 and let off the gas it starts vibrating and im not real sure its a vibration it might just be a rough ride i have had my wheels balanced, new u joints

 

Somewhere in the drive-line, or something loose in front-end?

 

ok i found these rancho rs 5000 on summit and the fronts say they fit f150 including 7700 GVW and i have a 7700 series f 150 but the rear ones dont say anything about 7700GVW
