no , my bad. I didn't notice which forum the post was in. I looked at the title, saw wheel seals , and jumped in . However, what I said still stands. As long as its in the shop , have the other three checked . It's simple to do . Any decent mechanic can check them in 15 minutes.
Yes check them. Our trucks have a rough job haulings poles. If you have ever seen someone load a truck with a wheel loader you would understand...not to mention where they are driven. Point being we have had the best luck with the Scotseal Plus XL. Seems to handle the best. Something else to check...there is normally a reason it started leaking...could be age...but could be other things...such as bearing slack as already stated. But I have found that more times than not the reason the seal goes is the vent in the rearend. It will be on top of the rearend and could be right or left side with either a hose or a disc that allows the rearend to vent as it heats up. If this plugs and it does from time to time the seal is the easiest way for psi to go. Do not blow air into this as if it is plugged the dirt will go into the rearend. Take it off...its easy and then blow through it and or clean it. We do this at ever service. This is also true for your steers and trailer hubs. The plug has a small hole...the size of a needle. If its plugs up you'll also blow a seal...the hubs get real warm running. What we do is take a coffee can of diesel around pull each plug and take a small paper clip and push through the hole...just make sure its a small one. Rinse it clean with diesel and blow through it then hold it up and make sure you can see light through it. Then you know its clean and able to vent. Just something I have seen happen to cause seal failure and is easy to prevent.
