Subject: Lurching/Bumping from Stop to Go on 2022 Ram 1500 4×4 with One-Piece Driveshaft

[Ramanski]

Hi everyone,

I have a 2022 Dodge Ram 1500 DT, Crew Cab, 6′4″ bed, 4×4, 5.7 L HEMI non‑e‑Torque, 3.92 gear ratio. My truck has a one-piece driveshaft.

Sometimes, when going from a stop to moving, I feel a lurching or bumping sensation. It doesn’t happen all the time.


I know on trucks with two-piece driveshafts, this can sometimes be caused by the center bearing, which can be greased, but since my truck has a one-piece driveshaft, I’m trying to figure out what could be causing this.


Could this be related to:

• Worn or dry U-joints
• Slight pinion or driveshaft angle issues
• Transmission or torque converter behavior at low speeds
• Play in the rear differential or pinion yoke

Has anyone else with a 2022 Ram 1500 one-piece driveshaft experienced this? What did you find was causing it and how did you fix it?


Thanks in advance for any advice!











If you want, I can also make it even shorter and punchier, so it’s more likely to get quick replies on a forum. Do you want me to do that?

does it do it in tow haul? Do you have start stop off?

 

[Ramanski]

Yes I does it in tow mode . I don't have stop/start.

Looks like a 2 piece driveshaft by the way. See attached picture . Maybe the carrier bearing or something in this vicinity ??

yes sir that is a two piece drive shaft. right there in the middle beside the joint is the center bearing.

Get under there and check for loose bearing housings on the ends of the joints. There should be no up and down or in and out movement on the joints. Also check the slip joint near the support bearing, that might be moving up and down, the slip joint should only be sliding in and out. Check the joint at the transmission output and the joint at the differential. Also check if there is in and out movement at the differential with a pry bar of some type or a big screw driver, but do not damage the grease seals near the bearing cups on the universal joints.
