    I run a 9'2" boss v blade on a F 350 6.0 psd. Has anyone had problems with the front axle? Anyone running alot of weight over the front end have problems with the bearings, hubs or anything else. Im just wondering, I know i cant get x springs or timbrens, but to my knowledge, the front axle itself is rated at only 5200 lbs. :D :D

    Fords have the best front end weight carrying ability in my opinion.

    The x springs, i believe thats what is on the f 550, will only help out the springs not the bearings, ball joints, and hubs. When there is alot of snow stuck on and around my blade i am over the limit for the front axle weight.

    Do the X springs just have more leaf's? or are they a different design?

    This is for 99 and up SD the X springs look the same as all the others two leafs. 6000lbs rating and 1.5" higher in the front. They are bent a little different side by side to the w's no difference maybe diff metal.

    I personally wouldn't go through the trouble of changing to X springs. They may improve your ride height and load carrying capacity on the SPRINGS, but it does nothing for your ball joints. This is where most of the stress occurs. You can put springs from a Mack truck under your psd but your axle is still the weakest link.

    As far as your spring weights are concerned, they are Ford factory guidelines. They can actually handle plenty of weight. The weight ratings are also designed for full time weight. Not temporary loads such as your blade which is only on the truck while plowing and spends most of the time on the ground scraping.

    On all the superduty's the x's are for plowing package you should really have them. Esp if you have the U or V springs..The X's will go down about 3/4 with 1000 lbs on the front...

    I'm not 100% sure but I think the ball joints are the same. I will look them up at work and reply back.

    I though i my f 350 had a Dana 50 not a 60. The bearings are what i was wondering the most about. Dyna trac offers a kit with new spindles, hubs and gets rid of the unit bearings. It also replaces the axle shafts with stronger ones. :D :D

    I believe the single rear wheel F350 has a Dana 50 (F250 too). The dual rear wheel F350 has a Dana 60.

    All this work for what... A couple more pounds of axle carrying capacity? Not worth the trouble. By the time he orders all the heavier duty components, he could have purchased a 450 and been kosher. I am all for upgrading and aftermarket hullabaloo but there comes a point where the cost doesn't justify the means.


    04superduty, glad I could help. Seems you got a great truck. I hope you have many years of use out of it. As far as the axle size... I am 99% certain the 250's have the D-50 and the 350's have a D-60. I will look into it further and get back to you. I know the 87 to 97 350's had D-60's. Gotta check into the new body styles.

    Even though the axle is "A "weaker link...the "WEAKEST LINK" would actually be the tires.
