I saw in a Ford book that the rear axle on my 02 F-250 4x4 SRW was rated for 6830 lbs. On the Visteon web site it states 9750 lbs, is either one of these weights right.
Thanks

look at the VIN tag in your driver's door. look for the GAWR for the rear axle. That is what your axle is rated at. The only thing you can go by is on the VIN tag.

No, those ratings are for F-350 SRW and DRW, not for an F-250. According to Ford specifications at the beginning of the 2002 model year:
2002 F-250 SuperDuty rear axle is rated for 6,084 pounds.
2002 F-350 SRW SuperDuty rear axle is rated for 6,830 pounds.
2002 F-350 DRW SuperDuty rear axle is rated for 9,750 pounds.
However, the 2003 F-250 SuperDuty rear axle is rated for 6,830 pounds. So sometime during the 2002 model year Ford began using the higher-rated rear axle in F-250s. So depending when during the model year yours was assembled, your rear GAWR might be either 6,084 or 6,830 pounds. As wil indicated, your GAWR is probably on the Federal certification tag on the lower doorpost behind the driver's door.

I special-ordered it new and plan to drive it until it quits.
The rear axle rating is limited on the SRW by the tire rating,
if you have 235/85 R16E's you have 3042 lbs x 2 = 6084
265/85 R16E's are 3415 x 2 = 6830
the dually tires would be 2778 x 4 = 11,112.
So I would assume the rating of the actual axle is 9750 lbs.
Which would make sense why Visteon says 9750, they sell the axle, not the tires. [img]/ubbthreads/images/graemlins/smile.gif[/img]
My truck is an 04, and the rear axle is rated at 6084, It has the 235 tires on it.
Of course, It's a dually now, but we won't get into that. [img]/ubbthreads/images/graemlins/biggrin.gif[/img]
My truck has the 10k gvw rating.(see signature for detail)
Steer axle is rated at 5600 lbs .Actual weight is 4860 lbs.
Drive axle is rated at 6100 lbs.Actual weight is 3300 lbs.

...I didnt know if Ford used the same axle in the F-250 and F-350 SRW and just put different weight ratings on the truck.

Don't confuse axle weight rating with rear GAWR. The rear GAWR is based the weakest link in the rear end, including axle, springs, tires, wheels, shocks, etc.
The axle by itself has a rating that might be different than the rear GAWR.
For example, in the 2003 model year, the rear axle of the F-250 and F-350 SRW was the same axle with the same rating of 6,830 pounds @ground. But the rear GAWR of the F-250 was only 6,084. So something else in the rear of the F-250 limited it to a rear GAWR of 6,084. Looking at the specs, the wheels, shocks, and springs were all rated 6,830 pounds @ground, so the limiter must be the tires. Stock tires on a 2003 F-250 PSD were rated at a max of 3,042 pounds each or 6,084 pounds @ground. [img]/ubbthreads/images/graemlins/smile.gif[/img]
Took my truck and 5th wheel to the scales last week, got seperate weights and was shocked,
Truck only:
Front 4510 lbs
Rear 3150 lbs
Total 7660
GAWR 8800
That leaves 1140 lbs for everything else. Im scared to list the weight of my 5th wheel because it wasnt a pretty site. Been hauling this camper for 3 years and never knew it was that heavy. Guess I will
have to trade-up for a bigger truck [img]/ubbthreads/images/graemlins/frown.gif[/img]
RoyFordGuy has it right. The axle rating is based on the sum of the weight rating of the tires on it. Nothing else. Not springs, shackles, or shocks. Ignore the door sticker. It is based on tires that probably did not even come on your truck. The Vehicle Code (California, anyhow) states it is the sum of the tires.

Jam, the 5r should only transfer 20% of the weight to the tongue. However that is the reason I got my dually. WITH my truck and trailer on the scales empty I only had 12-1400 lbs left for load transfer to the tongue. I went to a dually, it gives you 27oo more pounds capability on the rear axle. Smokey is the GURU when it comes to axle weights and such! Listen to what he has to say!
