mackniac Posted April 11, 2013 Share Posted April 11, 2013 The mechanic that work on my truck says that we need to adjust the thrust on the driver side king pin, (small play 1/8th) but the adjustement nuts looks pretty rusted, he says not to heat it too much cause de bushings are nylon made and might melt , is that right ? I was sure they were brass .So I want to go the safe way before going any further , he wants to remove the wheel the brake booster to have sapce to work on and even redo the whole king pin , I said wait a sec I want to think a bit .any one with any idea trics else ??

h67st Posted April 11, 2013 Share Posted April 11, 2013 I've done a few kingpins, they were always brass bushings. When we needed to heat them up to work on them, we would pump some fresh grease in them after heating to cool down the bushings. Quote Link to comment Share on other sites More sharing options...
blackdog2 Posted April 11, 2013 Share Posted April 11, 2013 The new ones are tephlon, the old ones are steel brass. Some times you could tighten them up for tempory fix Quote Ed Link to comment Share on other sites More sharing options...
felicello122 Posted April 13, 2013 Share Posted April 13, 2013 on the bottom take out the big cotterpin and tighten the x nut, can use a little heat on it, the bottom bearing has balls in it and it pushes the king pin up. too tight and it will steer hard. go enough to get the pin back in. You can do this for a liitle play, you have to remove the brake assembly and hub to get the x socket to clear. 1 Quote Link to comment Share on other sites More sharing options...
