My truck has a leveling kit on it with big oversize tires. I was having problems with the passenger wheel bearing going out I put 6 in over a years time. I then went to the cv axle on the passenger side. 3 months no problem and then I was turning around one day and backed off the road down a slight hill the grass was wet so my tires weren't grabbing so I put it in 4-hi and got unstuck. I got back out on the road and put it back in 2-hi. Then when I started driving I noticed a noise in the front end and thought it was a wheel bearing but it wasn't the cv axle boot is ripped and all the grease is out of it and I can't figure out what would have caused it.
Do you
have the same problem?

Has the suspension's ride height been altered? If it has, besides the legal issues, you've adversely affected the front-to-rear brake balance, steering response, handling, drive shaft angles, a non-adjustable alignment angle called "scrub radius", and the angles the cv joints go through.

I suspect you also have aftermarket wheels that are wider than the original wheels. With the original wheels, they were designed to place the vehicle's weight directly over the center of the wheel bearing assembly. Every time you hit a bump or pot hole, the forces were distributed evenly across the bearing. Wider wheels or those with a deeper offset place the weight further out, and that acts like a lever putting uneven force on the side of the bearing. Repeated bearing failure is the common clue.

You won't like to hear this, but you can solve all these problems by returning the truck to its designed ride height and reinstalling the proper size wheels and tires. Trucks with altered ride height also experience repeated universal joint failures. No suspension and alignment specialist ever lowers his car or raises his truck when they understand all the things that can happen. Also remember the world of automotive marketing is extremely competitive, and if a manufacturer can advertise one more inch of leg room, one more horsepower, or especially one more cup holder, you can be sure they're going to do it. If they could produce a truck with a lifted suspension, or a car that drags on the ground, and they knew there would be buyers, you can be sure they would do it. They don't because they know it can't be done without compromising safety and reliability.
Was this
