Hello,

All of the sudden, my truck started feeling spongy around turns and started "wandering" at higher speeds. Just knew something was up, didn't feel right. So in looking at it tonight, noticed that the right front is hard as a rock but the left front can be easily pushed down about 6 inches.
Looked underneath and didn't see anything obviously broken. If a shock absorber blew out, would it cause this? Seems pretty extreme.

Thanks,
