I have several units ready. Some members on the list have not contacted me regarding payment so therefor I am not holding my breath. First one with money gets the units I have ready. I think I have 11 or so ready to mail out.GOOD POINT!! I think I can vouch for how well they work, also. Seeing as how I have one installed.....Got any EXTRAS for him CTD!?
Welcome to DT and the elite group of Power Wagon owners!
Mine did the same thing awhile back. It was repaired under warranty so I can't help you with a solution...sorry.
I will try to keep this as short as possible and just hit the highlights, but you asked, so here's the story:
I usually do most of the maintainance and basic repairs to my vehicles myself. When we bought our Power Wagon, part of its duties were to tow our fifth wheel. I figured if anything would fail it would be the transmission or the differential (more likely the tranny), so while under warranty, I would let the dealership service the differential and the transmission, so if there were any problems they could not blame it on maintenance.
During the first 15,000 miles, many of those miles were towing the 5'er, including towing on I-70 to the Eisenhower Tunnel at over 11,000' and the rear axle was dirty from off-road, but still looking good.
15,000 miles and into the dealer (the one we purchased the PW at). I tell the service adviser I want synthetic and no friction modifier (I want no mistakes). Pick it up and the parts list has friction modifier. I ask what is this? I am told they always do that - it won't hurt anything. I ask - you always charge extra for something that is not required and the customer specifically said they did not want? Well, they refund the $ for the friction modifier and assure me there will be no problem, they do it all the time.
I leave 2 days afterwards for our next camping trip. The second day I notice the paint is bubbling on my rear differential cover. By the end of the trip all the paint is gone from the cover and the coating is coming off the axle housing it self and the cover is all rusted and looks like a 30 year old truck.
I consider it might have been cleaner they used has destroyed the paint, but I am concerned that for some reason the differential is getting too hot. Back to the dealer - they say normal - I say for 15, 000 mile it has been fine and as soon as you touch it I have this!
Next camping trip (now 4 weeks since diff service) and my "serv 4WD" light is on. Back to dealer and when I pick it up, the light is off. Next trip and now the "serv 4WD" light is on and the "rear lock" light is flashing (selector is in unlock position). Back to the dealer. Pick it up and lights are off, but it is difficult to get the rear axle to lock. Had read posts here that the more you use them, the easier they work and I figure whatever they did put it back in the "new" category, so I gave it a little time, but it got progressively more difficult to lock.
Back to dealer - I'm told "normal" - I say it wasn't that way for the first 15,000 miles or before you touched it. They take it in, I pick it up and it is the same as far as I can tell and continues to get worse until I can not get it to lock.
Back to dealer - I am told what I need to do to get it to lock (because I obviously have no clue in their eyes) - so I say show me! Strangely enough they can not get it to lock either (go figure - excuse me if I vent a little). They take it back - I pick it up - it will lock after driving about a mile!
Had enough with this dealer (this was not the only problem - but that is another story). Off to another dealer - a disaster I won't even go into - but I did not even let them touch my PW. Sometimes conversation is enough to determine incompetence.
I had been happy with the dealer we had taken the Durango to while it was under warranty - so off to them I go. I explain the problem and they assure me it will be fixed. They had it for 6 weeks (they worked with me for scheduling and loaner vehicles), much of that time waiting for parts and when they had it back together, the mechanic said he still was not happy with how long it took to lock and would like to keep it and I said DO IT! Mechanic said it was all messed up inside!
Finally I got it back and now it is great! The rear locker locks almost instantly! At 30,000 miles, I SERVICED the rear differential and used Mobil 1. It has worked perfectly. So now it is time for the 45,000 mile service and I am wary about using anything different.
Sorry for long post, but you asked.
I actually think this is another variable in the locker lights situation, "distance". Without fail I can be driving around town running errands and the RR locker light and Serv 4WD light will come on. Usually happens a few times a week and ends up going off by itself. Doesn't seem to have anything to do with moisture. I have dielectric greased all electric connections for the smart bar and lockers.Mine does the same thing, except my light turns off and the system works normal when it rains or when I tow a trailer. I moved from florida to north carolina towing about 5,000lbs for 700 miles and my flashing locker light was off the entire time until I got here took the trailer off and was driving around in the truck a day later and the light started flashing again and hasn't quit since. Its really starting to annoy me. Dealership said it was the "Final control Module" thats bad, not really sure what that is but they quoted me $1200 for it, $1,500 if they do the work to replace it!!
One other question to ponder. For those who have had their final drive module replaced (smart bar), have you ever had the issue again? I am wondering if the issue isn't due to a manufacturing issue with the final drive module. Just a thought.
