I'm with Walt. Check the speed senor and magnet first. Maybe it is your lucky day....

Default Re: Scraping sound then intermittent speed

Had some time today, so I proceeded. Removed access panel and figured I could remove sensor or possibly motor from above. Put in Tow, removed last negative from pack, removed first positive from pack. Unbolted canopy and removed. Attempted to remove body but tailgates and rear blinker wiring intertwined with frame (could just cut and re-splice in the future), so I changed direction and tackled from below. Brake engaged, chocked, broke wheel nuts, jacked up and removed tire. Didn’t have great access, so I also removed plastic wheel well. Unplugged sensor wiring connector and attempted to unscrew with screwdriver, ratchet and allen wrenches. All failed since it requires a torx bit. Not wanting to stop for the day and realizing that it’s probably the motor that made that horrible scraping sound (listing to me thinking I know what the hell I’m talking about) I proceeded to remove the motor. Took picture of wires into motor, removed 4 wires using 2 wrenches and removed the 3 bolts on motor. This is where I left off for the day. Will go buy a torx screwdriver and attempt again tomorrow.

Good days work. Just be really careful and double wrench those motor studs on and off to protect the internal connections.

I don't think you need to go any further. Today is your lucky day. Replace with a good quality sensor. Not Ebay or Amazon.

Good job!

And with that being a D&D motor, it may be like PQ and others and take a specific one since it is a custom built motor. I would definitely contact them before buying anything just to be sure of the specifications (size, diameter, etc)

Yep, already called D&D and they have the sensor and magnet as a kit for $40. It's shipping Monday, so once I receive and install, I'll post an update. Something tells me it just can't be a magnet but I'll put it all back together and see what happens. I tried to pull the motor but it wouldn't budge too much. There are some great suggestions to get it loose but I'll see if the easy fix works before I give it a try. Thanks for all the advice!

And it is not uncommon to hear a little (light) scrub from the brushes. Most of mine do it as they get older but does not effect there operation at all....

You said three bolts on motor, I think there are four bolts.

Pete, don't fix it if it ain't broke. It is major trouble if that armature is stuck on the shaft. Read through this thread.
