I finally took it to the horse trailer place that upgraded my entire axle, brake and tire assembly last October.
They found grease on rear axle brakes was the final problem. Due to my over-lubing and blowing out the rear axle seals. Not sure what was the first problem, but there were multiple things learned here by me:
1. I used my "Trailer Aid" to easily lift one tire at a time so I could adjust the brakes and lube the axle.
2. I lubed the axles before adjusting the brakes (Dexter EZ lube system). But apparently I pumped the grease too hard on the rear axle and the axle seals came loose according to the trailer repair shop. Looks like I'm not the first one to do this. Lots of posts on dexter ez lube blowing out seals.
3. the 10 gauge wire definitely eliminated the voltage drop, but I don't know if it made any difference. I did the over-greasing before upgrading the wire.
My guess is one or more of these were contributing to the problem:
- voltage drop from front to rear axle
- rear axle needed adjustment more than front axle
- grease on rear brakes (after over-greasing rear axle).
