Serviced mine this week
So inspired by tire failure stories and bearing failure stories, such as this one I went ahead and upped my tire load range from C to D and snooped around the internet to search out some American made Timken bearings to replace the Chinese bearings that came on my TT.
Took my wheels and tires into a local tire store who mounted them and assured me they were inflated to the sidewall pressure of 65 PSI.
While I had the TT jacked up decided it's time for the bearing change out. I followed the instructions in the Dexter axle manual and removed the old seal, bearings and races. I was impressed with the amount of grease and how well everything looked after a year and 8K miles or so. My TT has the E-Z lube system but I wanted to do the whole enchilada.
Anyway, I was very careful to keep everything sanitary and got the new bearings packed and installed on wheel number one. Took me about 2 hours and a roll of blue shop towels. Just for grins, I then injected grease through the E-Z lube fitting and was happy to see new grease coming out fairly quickly.
So, on the remaining 3 wheels, I just used my grease gun to purge the old grease via the E-Z lube fitting. Finished the remaining 3 wheels in about an hour.
This morning I decided to give the rig a hundred mile shakedown run. First thing... checked the tire pressure.... dang if all were right at exactly 45 PSI so pumped them up to the 65PSI, then rechecked the torque on the lug nuts.
Then 50 miles out the interstate and 50 back. I stopped a couple times to check wheel/tire temps and lug nut torque. Everything checked out A-Okay.
Also happy to report the TT seems to pull even better with the new tires. Virtually zero sway when being passed by the big rigs as I plod along at 63 MPH.
So, I am thinking I will not install the new bearings on the other wheels for at least 2 more years (unless I feel things running too warm). Just go with purging the old grease. I will, of course, carry the replacement bearings and seals plus tools when we're on the road.
BTW this is not nearly so messy if you remove the wheel before doing the greasing, replace w/o the center trim cover and use just a couple lug nuts finger tight. Then grease. Little more work lots less mess.
