Hey, I've got a question for anybody who has done this, how am I supposed to get the armature to line up to go into the bearing at the end of the housing with the magnets in it? when I try to push it on, the bearing just swivels and it won't go in.

That's a tough one.

I just reset the bearing and retried, over and over, until it went in.

Yup, in and out until it is centered perfectly, window motor is the same!

This thread deserves a "thank you" bump.

Saved $700 on a new motor by replacing the bad bearing.

The job was pretty easy thanks to the pointers in this thread.

Hybrid, smybrid. You still need grease with ceramic/metal.

Go full ceramic! Vollkeramik!



I want someone else to test if they make the wipers faster.

I don't think I will be getting a 45 dollar bearing for the wiper. Probably the hyrbid will work great.

yup, that's too high.

You can just remove the wiper arms and put them down where they belong in the 'park' position without removing the motor again. Just flip up that plastic cover at the base of the wiper arm, remove the nut, pry up the arm and replace it where you want it.

Reviving this because I just finished doing it.

The writeup and pics are dead on. Thanks to the thoroughness, I didn't have any surprises. That was nice.

I'm really glad the pics showed how dirty/rusty the inside of the motor could be. I would have been worried that it was junk with as bad as it looked, but it cleaned up nicely.

I also disassembled the pivots where they go through the frame. 2 C-clips and a few washers and the pivots popped right out. I cleaned and relubed them.

I got the bearing from a local supply house. Found them with an online search, called to make sure they had it in stock. Slightly less than $20.

Getting the armature back in was a challenge. I tried a variety of clips and clamps trying to hold the 4 brushes in place. What I stumbled on was using the old bearing as a "hole filler." I got the 2 top brushes in, got the bearing in place to hold them, and could then tilt the bearing far enough to get the other brushes in place without letting any that were in place pop back out. I could then put the armature through the hole in the bearing and get it far enough in that the new bearing would hold the brushes in place before the old bearing was pushed out.
I held the worm gear in the transmission with a small C-clamp so that the armature didn't get pulled out by the magnets when I put the can over the windings.

Because I tend to be overcautious, I reassembled it in stages, testing each stage. First I plugged in just the motor and made sure it ran and that it parked in the same place each time. When that worked, I attached the mechanism and set the pivots to far left (as viewed from the front) and made sure that it was moving correctly and parking at the far end of the travel. Then I installed the unit in the car, bolted it down and made sure it was moving and parking properly before I attached the wipers and did a final test.
Probably overkill, but the idea of watching the wipers go past the bottom of the windshield and into the cowl area wasn't appealing to me.

Definitely messy, very "fiddly" as far as reassembly of the motor, but not all that hard. Using the clamp let me get the can over the armature on the first try.

And this writeup gave me all the information I needed to do it.
Thanks Ken.

Could someone post a video of their properly-working wipers, so the rest of us can see how quickly the wipers move when in good working condition?
