Jim, That was my post below on the brakes and sure seals. The shims can go between the hub & backing plate, OR between the backing plate & axle housing. My IT manual shows a pic of the shims between the axle housing and backing plate. Your right, that is less than a perfect seal. The side where I saw the worst oil leak-by on the brakes was the side where the shims were between the hub & backing plate. That seems like a good reason to stick the shims on the back side of the backing plate so any oil wetting thru the shims happens outside your brakes. Gasket the hub to backing plate so you get no leakby into your brakes. I used a thin coating of silicone also for added insurance. Splitting-up the shims to each side is fine, and probably make the install easier anyway. I had one side with 5 shims, three of them where .005", very flimsy, pain in the behind to get them all lined-up with the hub studs, backing plate, etc. when installed behind the backing plate. I had a heck of a time. In the end, I pulled them back off, gooped each one with a couple daps of silicone and made a "shim sandwich" with all the shims. That made it a lot easier to line-up all the bolt holes. In hind sight, maybe I should have used grease for that instead of silicone though. I had painstakingly scraped down and cleaned each shim, no fun with those .005 shims! You may find some of your shims have worn unevenly due to the issue John mentoned below, shifting around due to loose bolts. I had a .005 shim that actually had holes worn into it and measured .003 - .005 depending where I measured it. Maybe you could just double gasket one side to make-up for your bad shim. The gasket material I got from the local auto place was .012". The old worn out gaskets I scraped off were .007". The Manual has a blurb about using "standard gasket material that is .008 - .012 for the axle housing(trumpet) re-install". I assume the same applies for the gasket for the hub & backing plates. The nuts holding the hub on are only torqued to 35 ft/lb... not very tight. After reading John's comment on how they tend to work loose, I decided to use locktite on mine, not the permanent type, but the type that can be broke loose with hand tools. sorry for the long reply... just went thru all the same stuff so it if fresh in my memory. George
