KING PINS???
-When did Ford stop using KING PINS on their famous "TWIN-I Beam" front suspension (2wheel drive)? I personally think THAT was a BIG mistake!
I had a '78 F150 (SuperCab) (aka-MY User name) with King Pins, a '79 f250 S/C C/S with King Pins, sold both with close to 200k miles on the original King Pins, always kept them greased, never a problem at allignment time-
NOW most everyone I hear is having problems with and replacing the darn Ball Joints, including our friend Frank......
I wonder if I can RETROFIT KING PINS onto my LATE '99 F350 Dually 2wd and get back to business?? I have constant weird front tire wear and its been checked and alligned by a BIG TRUCK shop open here since the early 50s owned by the same family.......
THEY also did the old '78 F150 and the '79 F250 and NEVER a problem with tire wear afterwards.......Comments?

First off 4x4 is a completely different situation than 2wd.
Second, when I bought my truck 5 years ago it HAD EXPENSIVE Michelins on the front and THEY were worn weird-I ended up meeting the original owner of my truck after I bought it from the 2nd owner who had it for a very short time-turns out the original owner was WAY more **** than I am when it comes to his vehicles, and he told me the front end was alligned several times while he owned it.
The Michelins were beyond saving at that point, I installed 6 new Cooper Discoverer H/Ts which I know aren't Michelins, but I feel are a decent tire, had front end alligned, they added some type of shim in 1 ball joint and pronounced everything else good. same results, I've spend $300.00 on rotations since the innitial install and same weird wear on the front tires.-what they are doing is if you feel the tires with your hand and rub towards the rear of the truck they feel sharp, rub towards the front and they are much smoother-this is on BOTH inner and outter edges, I run 80psi in the fronts constantly.

Didn't know that. I know when I bought my truck new the factory tires always did that. I went to Cosco with the michelins because they rotate for free, even dually like ours. Haven't had a problem unless I don't rotate. Its Ford for sure, but I like my truck.

Check the heavy rubber bushings on those I beams. They may look OK and align real good but under the stress of road and load if they are soft you wobble. Replace with after market hard plastic bushings. Preferable with a zerk fitting for lubing I assume that the alignment shop would check the tie rod ends but look at them too just in case. Another source of tire bounce is worn shock mount rubbers or even soft ones as well as the shocks them selves. It is the little things that can get you in this case.

Thanks Guys!! I'm, going to have a serious talk with the manager of the BIG TRUCK place when I get front tires-going to buy the tires from them and I guess anouther allignment and then make them responsible for the wear.

I am curious what is the difference from King pins and ball joints.
one better than another?
I just found out I have King pins on my dana 60 quigly axle.
so I am researching
I just bought a 4x4 van and getting inner tire wear and I thought the ball joints were bad.

Isn't that a bit high? I think the E tires are rated for something like 65-75, but I run them at 55 to get an even wear. You sure you don't have them over-inflated?

When I run 60psi in the rears I only get about 1 1/2" tread contact in the center of BOTH rear tires on each side.-I run 45psi in the rear when empty and air up when towing heavier...I keep 80psi in my fronts all the time...

Hmmmm. Well, it's been my experience with other vehicles (not PSD's, but then again, I haven't "tempted fate" either) that if you run the tires at the max rating, they wear-out in the center of the tire. I'm just wondering if that's happening to you.

The front of our trucks are very heavy with the diesel. I don't know if I run full pressure, but around 70 psi works well. Even wear on my front. The rear is different with my dually. Around 60 psi if un loaded, thats most of the time for me.

My tires were/have been wearing on the outside edges and slightly cupping before both on the EXPENSIVE Michelins and the mid-priced Coopers...I'm now running Firestone Transforce on the front.....
