Suspension kept bouncing.

There are these rail road tracks that I've crossed over going the speed limit (40 mph) and they are angled, but a couple times I've noticed that the driver side will keep bouncing like I'm still going over bumps. It doesn't always do it but the few times it has it doesn't always stop until I've slowed down a little, maybe 100 ft after crossing. Anyone have any ideas what's up?

Re: Suspension kept bouncing.

your shocks most likly need replacement the one on the drive side from what you explain might show oil running down on the exterior of the shock tube , there are a few tests to confirm this ,

Re: Suspension kept bouncing.

Also check the upper shock mount stud where it goes thru the chassis rail...they can elongate the mounting hole as the top mount is in single shear.

There are support brackets sold that mount to the chassis (needs some holes drilled) that puts the top mount in double shear.

Re: Suspension kept bouncing.

Turns out it was the upper mounting for the shock absorber it was elongated but I appreciate the quick reply that's why I love these forums
