Does anyone know what changed in the front end of the 2010 4x4's to increase the front axle weight rating to 5500lbs?

From what I've read here on this forum (or maybe others, I've drank since then), it's larger ball joints.

Hell, I've drank alot since then, I might have dreamed it up....

I think that I heard that the front axel U joints were enlarged and the associated hardware to accomodate the larger U joints.

What boiler guy said. Larger ujoints.

Knuckle, and u-joints for sure, not 100% sure on the ball joints. Weight increase and better turning radius are the results.

I haven't been under the truck yet, (only has 2400 miles) but I will have it on the lift in about 1600 more to service it. But I was just curious if the front end had more grease zerts than the older models. that was one thing i was a little concerned with, on all of my other trucks there were probably 6 or so zerts to grease all of the moving parts on the front end, and on my 07.5 it only had 2 (other than the phantom front drive shaft zert)

 

[Boiler Guy]

No grease fittings on the front end. Only point to grease is the front driveshaft double cardan joint.

 

[MattTN23]

Hmmm. Well I know a sealed unit is good. I just always liked being able to grease everything every oil change. Just a little mental security..

I wonder if the 2010+ trucks will have the ball joint problems of previous generations?

They have slightly different knuckles and the front axle shafts use 1550 series u-joints. They also increased the size of the lower control arm bolt at the axle.

I have a 2010 SRW Laramie Crew and it rides significantly worse than the 2010 2500s I have driven. I also have cooled seats which are pretty stiff themselves, so that doesn't help. It does have the 3 thicker leaves on the back versus the 4 thinner ones for the 2500. I haven't driven a 2010 2500 Megacab, but I have driven 2007, 2008, and 2009 and they all ride smoother than my 3500 SRW. I would assume the longer wheelbase and weight would help the ride. Mine's pretty brutal, I was able to get a better deal on the 3500 because they had it on the lot and they couldn't find me a comparablely 2500 so I was able to steal it, I love it, but it still rides like a tank.

I think you're looking for the 2500/3500 srw differences thread.
