just did zuk upgrade to the rear of my stock 89 runner.i used the jeep tj front springs out of convience(i guy in my shop was lifting his jeep so the price was right),since install whenever i reach speeds of 55 or greater on decel or coasting there is a horrible bang bang bang almost light a exhaust pipe hitting something type noise. i have put truck in the air numerous times and can find no evidence of anything hitting ie: no fresh marks on exhaust,gas tank,or anything.i should also say that i installed the ball joint spacers a day later and still no change. any help would be great thanks, steve

 

Maybe the toyota parts are attacking the jeep parts. I hear these two species don't get along.... no I have no idea but I would like to know
