Hey, I own a 72 TR6 and recently went through the front and rear suspension upgrade, i took out tube shock conversion and installed new lever shocks that have the upgraded ball bearings and do not leak as the original type did. The problem is when going over bumps a loud banging noise comes from the rear axle and so i went in and tightened all bolts and nothing seems out of order. I intend to have the alignment done and reinstall the sway bar in the rear that i had removed. I also tried inflating the tires to 32 rear 27 front. Any suggestions would be appreciated. Thanks
