  1. UPDATE: FIXED. Inner race on the front wheel bearing broke loose and allowed debris inside. Replaced and noise is gone. I now have 138k miles on my PTU and all is well. I installed the PTU drain plug (what a bitch) and replaced oil 3 times. Runs like a champ now!!
  2. Just had the live oil changed. Not much came out, but what did come out was shiny with metal. Still making the same noise. How many bearings are inside the PTU and are they hard to replace?
  3. That's exactly right. The rear bearings on the Edge are notorious for failing. There are several threads on here about failed rear bearings.
  4. Wow that was a very helpful write up on that link. I tried to hand pump out the old oil but can't get the suction hose past the gear into the bottom. The little bit I got out was still runny by definitely saturated with metal filings so I hope it's salvageable. I think that adding the drain plug on the bottom is the way to go.
  5. The edge rear bearings are that way. The front are slightly different. A bearing press is a tool that you hit with a hammer and u can rent from o'reilly or AutoZone and when u return it you get all your money back. The hammer was my most used tool, and I did both of mine.
  6. Oh, and usually squeaky brakes goes away when u apply brake pressure but this sound is completely unaffected by applying brakes. The only thing that stops it is acceleration.
  7. Replaced both front bearings about 8k ago and the passenger rear on July 30th, brakes are about 500mi old, yes I did them myself and I put high temp grease on the guide studs. Also did the bearings myself. I read on one of these threads that although the PTU claims zero maintenance that the oil often breaks down at high mileage and leads to PTU failure. It doesn't leak anywhere but I'd like to drain and refill it, but I'm not sure how or what kind of oil it uses.
  8. 07 AWD makes a grinding or scraping noise when coasting in gear or neutral, but goes away under acceleration. Brakes are new, bearings are new, transmission is about 35k old. Can be heard best on passenger side. Tires all match and have the same amount of wear. I'm at a loss.
  9. Actually it's much easier than that. Take off the tire, brakes, abs sensor, tie rod nut, then smack the SIDE of where the tie rod attaches to with a hammer until it pops loose. Take off the axle nut, slide out the axle and tie it up to keep it from sliding out. Pop out the race out of the spindle with a bearing press and a hammer, make a cut in the other half of the bearing that's pressed on. In other words there's 2 races, smack one out with a bearing press, cut the other one with an angle grinder and hit the cut with a chisel and hammer til it cracks and it'll slide off. Smack the new one in with a bearing press and hammer, the reassemble in reverse order. I did both my front ones in 1 hour.
  10. It's internal on top. The OSS also notoriously fails and sends tranny into limp mode, which locks it in 3rd gear. Pay a trans shop and keep the receipt for warranty. I had to do it with mine. Cost about $600.
