I decided to banch the crap out of this truck yesterday. man. it was covered up to the roof in mud.some of this carnage was not intentional though, one of our pipes decided to burst at 100 psi and made a mess. and all the other foremen were at least 5 miles away. and my phone was dead. so i has to go out to the puddle of mud sand and water to fix this thing, it was a mission. anyways, the point is i was in mud for at least 5 hours, enough to fill the rear tires in mud.. the looked like they were combined into one tire. i took it to town to get some parts, but before i did, i spun the tires to get some mud off. I got out and checked the wheels and tere were chunks of mud on them. i started moving and at about 45 MPH, the whole damn truck shook and i couuld see the mud falling off. i grabed the parts and went straight for the pressure washer to remove the mud. got back on the road and not a single shake at 85 MPH. so i have concluded that mud+dualie work truck+ mud terrain BFG'*= major U-Joint Sabbotage.
So there you have it, do not use 1-ton duallies for mud jobs, 3/4 ton heavy dutys work way better.

Believe it or not daullies were not built for the mud.. lol

I know, but tell my maniacle boss that. I think he'* missing a couple screws.

you could try take one set of wheels off it and run it singles i know in snow daullies are not good either and in the winter they take off a set of wheels for better traction
