No it's a 2 wheel, its a great truck. I used to pull a 24' 5th wheel, (1984) OK but now I have a new 25' with slide out and its more of a chore to pull. I'm thinking of installing a 4.10 gearset. What do you think?

it would help some, but maybe getting it to breath better,[k&n filter, exhaust] would be money better spent, maybe a chip? i like the rearend, overall. i pull a trailor 5000lbs. it does okay, i'm going for the k&n first then exhaust, just for alittle more H.P.i've been reading the forum's and that seems to be the most comman upgrades.

The 10.25" is the size of the ring gear in the ring and pinion set. As a general rule, as the ring gear increases in size, so does it's thickness and durability.... as far as I know the Sterling semi-floater is a desing based on the 9.75" unit found in the '97 and up F150's and Expy's. Sterling rears have been installed with the 10.25 inch ring gear size in 3/4 and 1 ton Ford trucks for more than a few years. Many of the early to mid 90's versions used a full floating design. This means the axle shafts themselves are not held in with "c" clips like a semi floater and both ends are sitting on bearings. The vehicle weight is supported through the tire/wheel and bearings, (hence full floating)... this makes it more reliable. Not like a semi-floater which uses the axle, shafts and outer bearings to support the vehicle....

Kerry,
Thank you for the info, is it diffcult to replace the front seal on this unit ? the first one was done by the dealer at 30,000 miles, its now at 119. and starting to drip.

Not too sure... haven't had to replace one myself. Once the yoke is out of the way it should be pretty easy. The yoke's the hard part.
As a note, the synthetic fluid may be the culprit. The stuff is awesome for friction and wear, but it'll find those microscopic cracks and really show itself unlike the dino stuff.
