All the ones that had drain plugs where those squared off ones, and after watching some of the Banks videos on diff covers squared off ones seems like a bad idea. Plus there may have been a clearance issue with the heat shield on the front of the gas tank. The nodular iron seems like a bad idea for heat dissipation. This is a Dana Spicer part fit on perfect, I used a gasket too instead of the RTV. The link is above in a post from where I purchased from.Re: Rear Axle Fluid Change Differential Cover with drain plug.Project done. 8 oz of Motorcraft friction modifier in there and 80W90 synthetic like manual called for. Old fluid wasn't as bad after I opened the cover up. New cover installed so should run cooler.

I have done lots of homework on this. A Dana 70-HD is the same axle housing and tubes as a Dana 80. The difference is the size of the Ring gear. The Ring gear is slightly smaller on the 70-HD.Re: Rear Axle Fluid Change Differential Cover with drain plug.Case of oil is 12 quarts. So a bit over kill, but the Exploder seems to burn it easily so I will keep it on the shelf. The Motorhome the oil is roasted no doubt about it. I am going to put the cover that the F-350 had on it, to help get some heat out. I ordered this one up. Diff CoverRe: Rear Axle Fluid Change Differential Cover with drain plug.^^ Thanks for the tip on the looking at the banks website. I really like there covers and would love to get one of them, however it looks like in 2007 ford went to a different axle on the E-450's as the ones they have on the banks website are 12 bolt covers. Mine is a 10 bolt cover.Rear Axle Fluid Change Differential Cover with drain plug.So here is the scoop, our 2003 Winnebago 29B is built on a 2003 Ford E-450 chassis. I am doing my annual maintaince, and decided this year is the year to fix my rear end seepage from between the diff cover and the diff. Chassis has 44,000 miles on it, so not a ton. Fluid is pretty stinky and black in there as well. So owners manual says 80W90 oil for the axle. I have a case of 80W90 synthetic on the way. Also have a case of 75W140 Motorcraft on the way as that is what goes in the diff on the towed car (2003 Explorer). So question what fluid is everyone running in there. Owners manual says 80W90, best I can find is 50k mile change interval, so I am almost at that. All this said being a 4.56 I bet this axle runs hot, so was looking to swap covers out for one with a drain plug. Has anyone done this? Which cover are you using? Also what oil is everyone using in there? ThanksRe: Models with Adaptive Cruise ControlLane Keep assist and adaptive cruise control.......I guess I can say "motorhome you got this" and then I can get up use the restroom and make a sandwich all the moving down the road? Yes I am very familiar with these features. I like them on a car and truck, just not sure about a motorhome.......Re: V 10 mpg ron.dittmer wrote: overdrive75 wrote: pushtoy 2 wrote: Thanks for all the replies. I guess I am right in the ball park pulling a 3500lb. car and fully loaded I am getting 6.5 to 7 on a mostly flat road but in the mountains all bets are off. I don't check it then. This is the real answer here. I get between 6.5 and 8 mpg depending on conditions, generator running or not. I am always towing a toad that scales out at about 5k lbs for the road. Hmm... Mine is a real answer too. My numbers are calculated at the end of the trip with consideration to our Onan-4000 generator usage of 1/2 gallon per hour. Our trips are between 4000 to 6000 miles so there are a lot of miles and conditions considered in my declared fuel economy. My mpg numbers posted a couple of replies earlier are as accurate as I could get. We do live near Chicago, so many of our miles are interstate-driven across the Great Plains. Now I could post better numbers yet if I considered the fuel economy of the tow vehicle. Those miles keep the motor home at the campsite. But I never track the tow vehicle so I am unable to consider it in trip averaging. ^^ Yours may be correct for yours, the front profile of yours is significantly more streamlined than a traditional class C with over head bunk area. My millage is reflective of driving 70 mph in all conditions. I do NOT take generator consumption out of the equation, as that is part of the usage of the unit. That sayd my 6.5 mpg to 8 mph statements accounts for generator run, head wind tail wind etc. If I look through my log book for miles since owned vs. fuel it comes out to 7.1 mpg. It is rare to not have the Exploder in tow, if it is not, there is a boat back there. I never factor the toad's MPG into the BRICK's MPG. That said, driving 62 on the interstate is a bit unsettling to me, hence why we run at 70 mph. Even on the hills, I just put my foot down and hold it there, the unit will find its own natural speed. I didn't buy this to safe money on fuel, it was purchased for a certain vacation lifestyle.Re: V 10 mpg pushtoy 2 wrote: thanks for all the replies. i guess iam right in the ball park.. pulling a 3500lb. car and fully loaded iam getting 6.5 to 7 on a mostly flat road but in the mountains all bets are off.. i dont check it then ^^This is the real answer here.
