lalkie64 Posted December 6, 2020 Report Share Posted December 6, 2020 52 B3B Looking for information on using nylon or brass bushing for the king pins. Rock auto has both. Are there king pin bushings that do not have to be reamed or honed besides nylon? Quote Link to comment Share on other sites More sharing options...
Jerry Roberts Posted December 6, 2020 Report Share Posted December 6, 2020 So they don't ream the nylon ling pin bushings ? I like the nice solid brass bushings that do need to be reamed . 2 Quote Link to comment Share on other sites More sharing options...

Tooljunkie Posted December 6, 2020 Report Share Posted December 6, 2020 Nylon is not a good choice. to each his own. there were nylon injection kits for king pins way back when, and only used as a temporary measure. pull knuckles and have a machine shop ream them for you. Not a big deal. 3 Quote Link to comment Share on other sites More sharing options...

Not a big deal. Nylon will work for me. More important is don't get the cheap kit with thrust washers. Get one with thrust bearings. Quote Link to comment Share on other sites More sharing options...
Los_Control Posted December 7, 2020 Report Share Posted December 7, 2020 years ago when I was a manager in a retread tire shop. I looked on in awe as they replaced a brass screw block on a $250k machine. Like a dumb ass, I asked ... why are you using brass to replace that? The engineer explained, the brass block cost $2k to replace, the screw shaft cost $5k to replace. The brass block is a sacrificial piece for the machine. Just something to think about when replacing parts on our old cars. Nylon or brass, just think about future issues. 2 Quote Link to comment Share on other sites More sharing options...
TodFitch Posted December 7, 2020 Report Share Posted December 7, 2020 Nylon will cold flow over time if a load is applied. So just sitting there with the weight of the vehicle they will go bad. No way in heck would I ever use nylon king pin bushings. Not a big deal to ream brass bushings and if you can’t do it yourself that should be a very cheap operation at your local machine shop. 1 2 Quote Link to comment Share on other sites More sharing options...
NiftyFifty Posted December 7, 2020 Report Share Posted December 7, 2020 Brass being reamed has a better chance of a nice fit, I’m inclined to think nylon would leave a lot of room for fit Quote Link to comment Share on other sites More sharing options...

lalkie64 Posted December 8, 2020 Author Report Share Posted December 8, 2020 Thanks for the response. The majority of other sites indicate not to use nylon because it does not last. I expect to use brass. Thanks Larry Quote Link to comment Share on other sites More sharing options...
lalkie64 Posted December 10, 2020 Author Report Share Posted December 10, 2020 I have found a moog 8453b king pin set that indicates it has steel bushing. Do these need honing? Mostly I have seen brass bushings on nylon bushings. Larry Quote Link to comment Share on other sites More sharing options...
billrigsby Posted December 10, 2020 Report Share Posted December 10, 2020 NYLON, never heard of such a thing? Use brass and be done with it! 1 Quote Link to comment Share on other sites More sharing options...
lalkie64 Posted January 11, 2021 Author Report Share Posted January 11, 2021 Still asking if steel bushings need honed or reamed? I purchased a Moog set 8453B Pin size- .875 iD split bushing size .868 OD split bushing OD size 1.003. Any help would be appreciated. Thanks Larry Quote Link to comment Share on other sites More sharing options...
Tooljunkie Posted January 12, 2021 Report Share Posted January 12, 2021 That is a difficult question, as the condition of knuckles is unknown. Split bushings should go in easy and shaft can be tested for fit. Quote Link to comment Share on other sites More sharing options...

maok Posted January 12, 2021 Report Share Posted January 12, 2021 Apparently when the bushes are press in they then need to be reamed to the correct sized because there is a reduction in the diameter. Quote Link to comment Share on other sites More sharing options...

Yes, as the bore where bushings go in can slightly vary. Once knuckle is off, it can be taken to a machine shop for reaming. Or, buy a reamer and do it yourself. They arent cheap, as a king pin reamer uses a guide to keep both bushings in line. Quote Link to comment Share on other sites More sharing options...
