sun shell is shattered and will need replacement.

You need a rebiuld. I did mine last summer. The same problem. Rebiult cost me $1400.00. But, the sunshell is the problem.

sunshell failures are usually caused by driver's that don't completely stop before they switch from reverse to drive or viceversa.
