Not so Good Vibrations

[whtbronco]

The suspension or wheel speed vibration I have been chasing recently is not consistent. This morning it was pretty bad for the 35 mile trip to work, and it starts out around 37-38mph. On the way home this evening it was fine until I was just 4-5 miles from home. It changes based on load, such as my son in the back seat. No matter what I pushed, pulled, pried, turned listened to etc I could not find anything loose and out of round. This evening I was gonna mess with the strut adjustment knob and noticed a gap in the rear strut lower bushing and thought that could probably cause this. It's always under serious tension so I wouldn't be able to feel anything by hand, rolling down the road though would be a different story. Whatcha think. This is the right rear, the left rear is the same, the front lower bushings are not visible while mounted.

New rear struts are enroute. Rancho has a lifetime warranty against wear out, yet another advantage to Rancho in my book.

From the Rancho web page:
DRiV warrants qualifying Rancho products against defects and wear-out when used on private passenger cars and light trucks under normal operating conditions as described below.
