How long do your wheel seals last??

if it was red, that sounds like power steering additive. lucas oil stabilizer or hub oil will not hurt anything in the hub. have used lucas oil stabilzer in my hubs. 7 years now. no problems.

 

You're right the red stuff is power steering stop leak.

That isn't what they put in.

 

My truck has digital temp gauge read out on the axles. Im not sure how low the gauge goes, but ive seen the temp read down into the single digits. Its really taught me to start off slow on cold mornings, and to hold that slower speed on the interstate until that oil gets warmed up and flowing. I can also feel that increased drag holding the truck back when its that cold, and its also verified by watching the MPG gauge as well.

 

I have installed different brand and model seals on trailer to see which one goes more miles. what I can see that SKF 46308 and national 38 gold seal are winners...

 

Never touch them seals. I used to check them and add oil now and then in the old iron days, but the new builds in the modern trucks are left alone. Unless they start throwing a leak or show signs of trouble. I don't keep a truck long enough for them to go bad. It is much likely for the tractor to be disposed of and replaced in a few years if that than to wear out seals.

 

My seals seem o last forever. I only use stemcos when the stub is damaged and a wear ring is needed, otherwise I use national seals and very seldom change one, truck or trailer.
If running off road, make sure you keep the hole in the center of the rubber on the steers and trailers open and the vents clean on the drives. I am in a lot of mud in summer and snow in winter, so have removed the vents and installed hoses on the rears, much easier to keep open.
