Has anyone confirmed either of these number will work?

Need to do some seal work on a HT and don't want to order parts that won't work.

Thanks,
Steve

PS The seal / wear ring combo as in the second seal is common in heavy trucks now. You always get a new wear surface when you replace the seal this way.

i know one person that has used them with no problems.

also the second seal is not a wear ring combo. it is as stated above.

I will get some ordered. Thanks.

Also, yes it is actually a seal / wear ring combo that is designed to be installed by hand without any special tools. It is a "one piece" unit and not designed to be separated. If you look at the diagram the inner piece in the "L" shape is a rubber in-cased wear ring with the outer piece being the seal. These are normally used in rough service applications as you can see by the diagram that there are actually 4 different "wipers" in the seal. Some of the wipers are for oil and some are to keep the dirt and contaminates out.
