My MicroBlue experience

I bought and installed MB tractor bearings back in April of this year. I am very comfortable in saying my MPG improved a minimum of 3/10 consistantly since then. In May I went ahead and ordered them for my trailer also. When I received them at the end of May inside was an installation guide. I asked my mechanic and the local shops if they would install them as per the guide, they all basicly told me they know how install bearings and I wasn't comfortable any of them were going to do it the way I had asked. I called Craig about also doing my transmission and rear ends, just to get some pricing and how to go about doing that when the time comes. We got to talking about the trailer bearings and he referred me to get them put in at charlotte truck centre. They referred me over to Race City Diesel in Mooresville NC to install them. This last run I did I went right through there and made an appointment. They were installed Friday June 1. Craig himself came over to RCD to set the end play exactly as it should be. Mine were set to ABOUT 0.006". I say about because when the new wheel seal is installed it gets compressed, making it up for debate as to where zero end play truly is. Craig can explain this better than I can. The guys at RCD knew their stuff, listened to how I wanted them installed, and even stayed late to get the job done. They charged me exactly as he said before they even started even though the job actually took longer because it was a learning process I guess you could say. Craig was there for the whole installation.

I was impressed by the tractor bearings in the beginning. Truck rolled so smoothly. When I left that shop to head for my delivery in Toronto, ON, it almost felt like the trailer wasn't even there. The small hills going north on 77, I had to pay more attention to the speed when going down the hills. I will say this, MAKE SURE THEY ARE INSTALLED PROPERLY!!!!! The end play is of utmost importance. Don't let a mechanic that won't show you the endplay when it is being set to do it. Don't accept the "I've installed hundreds I know what I am doing" thought process.

I know some people are skeptical, there always is. My idea to them is this - either stay the way you are and don't try them and I will get better MPG than you, resulting in being more competitive than you are, and therefore don't say "its BS" or "you are being paid" because I am not. Or buy a set for your truck or trailer, try them, and come to your own conclusions. I am not looking for opinions from anyone. I am only here to tell you my experience, (SO FAR) with MB. In the coming months (when cash allows) the transmission and rear ends will be done.

My mpg (only from fill up Wytheville, VA to Toronto, ON) was up about .2. This is even with a fault code that came on that the ecm wouldnt allow it to go full throttle. That will get looked at on monday. Hopefully it's only a sensor ... By the way I haul reefer and it is mostly 70k+ 90% of the time.

 

SORRY!!!!! can i have a mod please move to garage????? THANKS!!

 

it is definetly worth it. Not sure as to how much about pricing and what not I am allowed to post on here, but by my calculations payback on each (truck and trailer) is less than 1 year or 100,000 miles.

 

So the hard rubber stemco seal isn't compressible at all when installed? How do you determine true zero end play? Tighten it til you cant anymore and call that zero?
