2000 w/155k miles ABS engages when braking and turning left

tech II,

Perhaps we are talking about a different style of GM hub/rear end, or maybe I just don't understand.

I am going to try and upload a few pix to show you what *I* am seeing. maybe that will help both of us. Tnx.

For some reason, I don't remember the U-vans being like this.....I worked on Transports/Montanas and the harness was definitely not hard wired to the sensor, and you didn't have to take anything apart.....you show a picture from the rear and bottom...I think you access the connector, looking at it from the front...there has to be an opening in the tube on the front side.....

Well, I just found my manual last night and opened to the pages below. Is this bearing THAT easy to replace? Remove drum, 4 bolts and out?

If so, I may just have a go at it. At first, it looked like I would have to get the giant brake spring off, backing plate, slave cyl etc. (I don't have a tool for the return spring.

But if it's as simple as it looks.... I may just go for it.

Yeah, thats pretty much it. It may be a little stuck in the axle housing though.

What's the best way to get it out? Slidehammer attached to the wheel spindle? Prying? Brute force?

Also, do you think I'll have enough play in the wire to get my hands in and disconnect it?

Tnx

Slide hammer would be good, should have just enough room for the plug in the back of the hub.

Update. Towards the end of this debacle, I had 4 codes set C1216, 1223, 1227, 1234 (x2). The 1216 was a hard code. I would reset the ABS light and within seconds, the 1216 would come back.

I replaced the hub this AM. Took about an hour. I did not have to remove any brake parts. Pretty straight forward. Remove wheel, brake drum, remove four bearing flange bolts, attach small slidehammer to hub. 2-3 very easy taps of the slidehammer and BOTH the hub AND backing plate came off together. Hanging by E brake cable and brake line. Had just enough room to get the ABS connector off. Note: I could not get the connector off via the two access holes provided. They are too small.

A few more hits on the backing plate with a small hammer and the hub popped right off the backing plate.

Cleaned and lubed the bearing surface, connected the ABS, remounted the hub, reset the ABS light, test drove 2 miles. Mission accomplished.

Thanks to all for the help. Here are a few pics.
