got a question, little new to this. i just bought a 1999 ranger xlt, the previous owner installed a suspension lift kit not for sure what brand. i think it is a 3" lift and has 33" tires. my problem is when the 4wd is engaged the front driveshaft counter weight hits a cross member, cause a knocking noise. this occurs when going straight and even worse when turning (poss. binding?)... not so noticable pass 10 mph or under acceleration. i tried shimming transfer case, helped a little. any help or suggestions

thanks
