Been hearing and reading about Cummins, Emission and Aisin failures on the 5th gen Ram trucks.

Well, except for some 2022/2023 models. 🙂

But you were comparing the two.

I was comparing the 05 3500 to the 07 3500 to make the case that the gooseneck is the root cause of more front suspension work on the 07.

do either of them have an Aisin tranny?

In their dreams... :W

I had a 70 2500 ford with the twin I beam front end. compare that to any new truck. I think I know the best would be a newer model of any brand.

We know that unless somebody is setting the rig up to pull the nose heaviest trailer possible, weight on front axle will not go up much. This means the suspension travel will stay near same.
What about steering travel? With a trailer, to avoid hitting things on the inside of turn with trailer the TV will start to turn late, but turn sharper, compared to same corner W/O trailer. And backing? Most drivers oversteer. Could this account for the increased wear you see?

We have two 3500 Dodge trucks with 5.9 Cummins (The good engine)and one is 05 SRW and the other is a 07 DRW. The 07 pretty much has a gooseneck cattle trailer hooked up to it at all times and that thing is always needing some kind of front end work.

So you are comparing a 07 to a 4th gen truck, HMMMMMM.

Why is that wrong? They both essentially have the same front suspension design that dates back to the AMC Jeep Grand Cherokee design with a 5 link setup.

The design may be similar, but the execution and materials are lightyears different. The front suspension on my 2018 looks like it could be used under a semi. The tie rod ends, and ball joints on my 2001 looked to be the same as what is used on passenger cars, while the same parts on my 2018 are massive. Absolutely no comparison in strength and durability.

My original comparison was a 05 and a 07 which they both have essentially the same 5 link front suspension. Of the two the 07 seams to have more suspension work in which I believe is because most of it's miles is pulling a goose neck cattle trailer. I could be wrong.

I do agree your 2018 suspension is significantly better than our 05-07 trucks suspension, but that's another topic.

FWIW, the difference between the front end under my 2001 Dodge Cummins and my 2018 Ram Cummins is amazing. The 2001 looks like it was put together with tinker toys compared to the 2018. Those parts are massive. I rebuilt the front end on the 2001 at about 70,000 miles.

Simply NO COMPARISON!!!

I agree...

The 2001 design originated from AMC and the 2018 design originated from Ford

The dry weight was steering 5300, drivers 6840, trailer 6700, total weight 18840.

So only about hundred pounds transferred to the front axle with a 13,600 pound payload (above the weight of the trailer). I imagine I could influence that somewhat by where on the trailer I put the machine. I placed the back of the tracks over the front axle on the trailer.

So you now believe that not a significant amount of weight is transferred to the front axle, yes?

LOL yea I believe it now. Hard to argue it, the numbers don't lie.
