I have spoken with Tire Kingdom pretaining to my 04 F350 SD 4x4. At times when I am running around 38 to 45 I get a front end wobble. They are going to do a check next week since there schedule is booked for awhile. I spoke with the head FMC service department head who knows me and the family and helps me out, he says it might be a bent rim, I'll have to find out what it is since I have CarMax warrenty. Whatis everyones idea on the wobble.

I'm getting my coolent drained/flushed/simple green/vc-9 then final flush and refill at the end of the month (since I bought this truck used and of course don't know what the previous owner has done).

When i'll do my next oil change and I also chaning the rail and engine fuel filter/ drain the water seperator put the upgraded HFCM plug on and also put a coolent filter on to help get gunk out of the coolent.

I have read about a updated flash for the SD, when I talked with the tech he didn't know to much about it and he told me if I can show him the information on it he will check to see if I need it and all.

 

how many miles???

check balljoints

and the front axel steering knuckle ujoints and drag link/pitman arm

any odd tire wear

any odd impact marks on the rims

 

40k, I have looked at the balljoints and they look fine. I have found only 4 grease points and have added some grease to them, all the other grease points are non-servicable points.
Tires look good, they seem to be wearing good, I have looked at the rims and they look fine, but speaking with the FMC tech the tires look good and all, I'll get them rebalanced and rotated just to be sure.
I have had the truck in the shop a week after I got it with 38k miles on it, the alignment was good, but the steering wheel was off center which got corrected.
When I get TireKingdom to do the free check I'll be able to confirm some of those same items, since I don't have a lift and and full supply of items to check everything.

 

Front axel u joints are easy to check

turn steering wheel full left truck needs to be in 2wd get out and spin the axel each side by hand right at the u-joint
Both should turn freely with no slop at u joint

turn truck to right and repeat

and one more time tires pointed straight ahead

Ball joints alittle harder to check I couldnt tell on mine till I took the tires off but usualy have odd tire wear cupping ect...

If they find a bad ujoint or ball joint make shure they put greasable ones on I beleive that they sell a greasable motocraft one now
Im happey with the Moog stuff iv put on I hear spicer is pretty good to
