Hi,
Been having a bad vibration in my explorer. It happens ONLY when I let off the gas a little and feather it (trying to maintain speed). Under acceleration - no vibration. Foot completely off the gas - no vibration. It happens at 60 mph and over. The faster the speed, the worse the vibration gets (when feathering the gas). Not being able to figure it out I finally took it to a Ford dealer. They told me I needed u-joints on the front and rear drive shafts. They changed the rear driveshaft u-joints ($228) but didn't do the front ones because they said I needed to buy the whole new driveshaft ($600). I took the vehicle home and did some investigating. Couldn't find a rebuilt one anywhere. I found this place called Rockford driveline. (www.rockforddriveline.com) They manufacture new driveshafts. Supposedly a new better design, or you can buy the original design (u-joint one end, CV joint the other end). I bought one for $313. Brand new shaft, original design. I installed it last night and now the vibration is worse. It happens at all speeds but only when I let off the gas. I'm thinking the new drive shaft is either out of balance or manufactured with too much runout. Anyone have this type of experience? Putting in a new shaft and the problem got worse? Any experience with Rockford Driveline? Help!!!
P.S. The old CV joint boot was split and the CV joint had seemed to be worn some.
Thanks!
