Newbie Question
Good Evening ,
I'm new to this forum and this is my first post, so hi to all
.
I recently acquired a 1971 F 100 and presently attempting to replace the king pins and bushings. I know there have been a lot of posts on this topic but I've not found one that addresses my issues.
I purchased the Moog nylon kit ( part # 8524N) and it appears that it won't fit even though
the auto parts supplier insists it is the correct kit.
When I manually collapse the uninstalled bushing to a tight fit on the new king pin the O.D. is 1.09". The I.D of the bushing bore on the steering knuckle is 0.95". Obviously it will not fit. I could go the bronze bushing route but
the best quote locally for reaming and fitment is $85.00 PER SIDE.
From the build code this truck came off the Michigan assembly line
and first purchased in Nashville, TN
Any advice will be greatly appreciated.
Regards,
Carl

Looking at my Moog catalog, 8524N is the correct number for your truck if nothing has been changed.
I have always used the metal bushings and just taken them to the machine shop for install. IMO well worth the price.

I've always used the nylons bushings. They hold up well if your not constantly hitting curbs and pot holes. The last set I installed lasted 20 yrs. You just need to make sure you grease them regularly and the correct way. Most do not unload the kingpin to grease them correctly, applies to both (nyl/brz). But the bronze are a lot heavier duty if your going to abuse them.

Thanks all for the quick replies. The old bushings were Ford Delrin (nylon)
and were basically disintegrated, but I cleaned up the bores with a emery
and a light honing. As stated in my first post the I.D. of the cleaned up bores
is 0.95" but the new nylon bushings have an O.D. of 1.09". According to Ford
manual the nylon bushings are a press fit with no machining required.
Maybe Moog packaged the wrong bushings, possibly from a f450 or even heavier
duty application. Is there any source to verify the original inside diameter of the
bores in the spindle ***'y? Maybe I'm a victim of Ford's assembly line quality control.

Why are you blaming Ford?
You did not buy a Ford king pin kit, you bought...what we partsguys call a gypo non Ford kit from Moog.
And...are the spindles on your truck marked: C8TA-3106-D & C8TA-3107-D? If so...here's the correct kit > >
C8TZ3111A .. King Pin Kit / Nylon Bushings / Fit: 1966/71 F100.
While this kit is no longer available from Ford, there are 14 Ford dealers that have stock in their obsolete parts inventory, plus there are 8 Ford obsolete parts dealers that have over 60 of them available.
For example:
Green Sales in Cincinnati OH (greensalescompany.com) has 15 = 800-543-4959.
Collectors Auto Supply in Oroville WA has 22 = 800-414-4462
Wesley Obsolete Parts in Liberty KY has 17 = 606-787-5293
IF the spindles on your 1971 F100 do not have those Ford ID numbers, then what are they marked? Someone could have changed them.
The spindles used in 1965 are different from 1966/71. The spindles used in 1972 are different than the previous two types. Ford changed them again in 1973 and again in 1975.
All these different spindles use different king pins.

Actually, Ford bought them from Federal-Mogul, Moog, whoever...but they were made for specific Ford specs for specific Ford spindles.
A king pin kit that fits 1966/71 F100's will not fit anything else.

i usually just crawl under my truck whenever i change my oil, and grease it up till it starts coming out of the crevice.

Your suppose to jack the arm up, leaving the spindle unloaded to allow the grease to go into all the pin and thrust bearing.
If you leave weight on the spindle, then the grease will not end up everywhere, as it will be loaded on one side.

I first heard the term "gypo" from a long time parts manager who had been around since before the first Model T had been introduced, which was in October 1908.
