4th Gen MAX Limited Driver Running Board = Dead

[goodguy2k]

Hey all - looking for help on my wife's 2020 MAX Limited. The driver's side power running board is shot - motor etc work but seems the bearings are out and all it does is make that terrible sound (similar to a seal barking.) I've soaked the bearings with PB Blaster and lithium grease but nothing helps - thus I've turned them off in the menu and now looking at alternatives. I'm happy to go with fixed/non-power. Is there ANY source for nerf-bars or aftermarket bars for the 4th Gen EL/MAX? Can't even find at auto-wrecking yards. etc.

Thanks in advance.

The factory non-power ones are probably best. These should be the Max version. I would assume they fit with little work but don't know that for sure.

Is it possible to rebuild the motor?

Thanks all. AJ82 - that's the exact part, thank you! $800 per...

Mr Big - the motor itself seems fine. My sense after reading/You-Tubing etc is that its the bearings/bushings on the hinges that are at fault. The fix generally is to pressure wash and use PB Blaster to break up any funk, then heavily lubricate with llithium/chain grease to keep funk and water from intruding. The bad bearings cause resistance and the motors are designed to reverse if they sense resistance (whether funk or somebody's foot.)

I think before replacing the entire running boards, I would try Penetro or Kroil oil. They both work great. I tend to lean towards Penetro because Kroil could hurt seals.

Thanks Mr Big - can of Penetro is on its way. Agreed - I'll try anything to avoid replacement! There's an extensive YouTube about replacing the bearings (improved are available on eBay from the UK for ~$45) but requires a lot more labor. I prefer to work smarter!

I saw a limited driving today that had the fixed XLT running boards.
