Front Axle Shims
I've been doing some research on here, but thought I'd ask..... Is there a type of shim that would be used in the front axle where the king pin goes? I have a some light 'play' and looseness there. Or do I just have to look for another axle someday? Are there oversized king pins?

Re: Front Axle Shims
Does installing and tightening the locking pin remove all of the movement??

Re: Front Axle Shims
Yes, there are shims that go under the spindle. They're available from the vendors. They come with the new king pins. When the kingpins get loose (death wobble) the bushings in the spindle get replaced. There are two to a side, upper and lower. The king pins are .812-.813 and after the new bushings are pushed into place, they must be reamed or honed to a close fit. I prefer an .812 adjustable reamer. Don't try to get it all out in one pass. These reamers are NOT meant to take a heavy cut. Put the reamer with the square end into a vise and rotate the spindle down to it.

Re: Front Axle Shims
Post #3 ! Install the locking pin, tighten the nut, tap the pin opposite side of the nut, retighten the nut, should remove movement of the king pin.

Re: Front Axle Shims
How much play is in the king pins ? This has been addressed.
But, since you took it apart, might as well have new pins and bushings installed. |

I don't really have a good way to measure it. Perhaps.....the thickness of aluminum foil, if I was to guess. You don't need any tools, just pull it out. |

Are talking bearing shims or pin bushings. The bushing tolerance has been previously addressed. As for the bearing shims, most stopped worrying about that decades ago. I still like to use them, but, they are not going to cause a wobble issue. |

I really wish I could post a picture. I have some extra clearance or wiggle were the king pin drops into the axle. Just that, no spindle added. Maybe they don't fit that snug? I don't know. Just picture a bare, no parts added, fresh axle and you drop the king pin or spindle bolt in. It wiggles. Bad or good? |

Re: Front Axle Shims
It shouldn't wiggle.

Re: Front Axle Shims
Those axle holes can be sleeved back to standard. The king pin should be a hard hand push or light tap fit.

Re: Front Axle Shims
I had bad wear in the axle as well, and I ended up replacing the axle. I’ve heard pro and cons on repairing the axle kink pin hole.

Re: Front Axle Shims
There should not be any slop, play, looseness in the king pins! Period! It should be a "tap Fit" into the bushings. In other words, you should have to very lightly tap the king pin into place. They should not fall into the bushings. Can you see any scrapes or scoring on them? They are suppose to measure 13/16ths or .812 -.813 dia. If they are scored up or under size, replace them. Then check the fit again . Usually the bushings go first and you'll have to replace both.
Good Luck! Terry |

Re: Front Axle Shims
I think we're talking about 3 different issues.

Re: Front Axle Shims
Pictures to big. Find a way to resize them smaller. There are many apps with a search.
