Timing belt

Is it normal for the timing belt to wear out fast on our yj's? This is the third time i need to replace it within 6 months because of the screeching noise it makes. I do go alot of 4-wheeling I'm assuming that's the cause but just want to double check with you guys.

Which engine do you have? Or do you mean the serpentine belt?

He's gotta mean serpentine belt. I've never heard a timing belt screech. Maybe not tight enough if it's screeching???

Honestly, I know its going to sound dumb, but when I was younger I had an auto shop teacher who was all bubble gum and tin foil under the hood. He taught us the older belts have broken down and release a bit of oil on the pulleys and that keeps them from screeching, if you have the car running and hear the screech, put a bar of dove soap to the belt for a few seconds, if the noise dies its not the belt, just the lube.

If it IS the serpentine belt always spring for the more expensive choice, especially if you have an upgraded alternator. I went through two cheap belts in three months with a Mean Green H/O alternator and it was noisy =). Good to go with Continental.

pop the hood and check your harmonic balancer for wobbling. It should be practically NONE! If there is anything significant then there is your answer. First - will chew through a belt like you through your breakfast in the morning and will be making those annoying noises. Second - on top of that if its big enough it might start scratching the chain cover behind it. I believe it goes for both 4 and 6 cyl. engines but anyone is welcome to correct me if I'm wrong
