This whole journey started when I noticed gear oil leaking from where the axle tube goes into the pumpkin on my front axle. I knew my axle was a little bit bent from a previous alignment showing negative camber out of factory specs. The other day I decided to throw a dial indicator on the axle to see if there was any movement between my axle tube and diff housing. As I was jacking up the truck from the bottom of the pumpkin that dial indicator started to move. Right around .0023" of movement OUCH! Fast forward a few weeks I purchased an AAM 9.25 housing from salvaged 2500 Hemi with no front end damage and it appears to be bend free. I also plan on rebuilding it with new seals, AAM U-Joints, ball joints, and an Artec truss. Here's a few questions I have and wanted to get some input. My truck is a 2012 Ram 2500 with the Carli 2.5" King pin top kit. This truck sees quite a bit of hard desert miles along with the potholes and poorly paved roads here in California.

Would my 120v Lincoln Pro Mig 140 be underpowered for welding the 1/4" mild steel truss to the axle? If so I have a buddy who offered to help TIG weld the truss for me but he specializes in welding thin stainless steel. I used that 120v welder to weld on an Artec truss on my old Jeep Cherokee with a Dana 30 but that was a whole lot lighter and thinner material. I was even thinking about MIG welding the areas where it's mild steel to mild steel and having the cast steel areas TIG welded.

Would It be beneficial to weld around the axle tube where it joins with the diff housing? I've heard a few say no because it'll weaken the casting.

Lastly, would it be overkill to throw in the inner axle sleeves made by Synergy along side of the axle truss? I installed a set on my current axle under the truck but sadly my problem wasn't a bent axle tube.

Just add a support to knuckle
Have a pro weld in small amounts so not to warp axle

Your mig will be fine, make sure to preheat the housing before welding.

Thuren truss. Super easy no fluff no extra stuff. Weld it and be done.
