Re: 1986 Chevy K10 Rear Upper Shock Mount Frame Cracks

The biggest thing to lead to this the shock is to heavy duty for your set up, shocks bolts get loose shock has more play the head bashes up and down mashing the hole in the frame working the hole bigger or cracking the frame in the long run. To fix this now and then check the shocks(all) mount bolts and re-tighten then if loose.
