4 tires changed, 4wd runs rough

xfreak · #1 10-25-2005, 08:17 PM

I recently put in 4 new tires and shocks (Monroe sensa trac) on my 1999 isuzu rodeo 4x4 v6. Now when I press the 4wd button the truck runs really rough(grinding noise). Also on 4HI, if go about 50 mph, the 4wd gear shifts down by itself and truck doesnot move at all. I have also noticed that the 4wd doesnot disengage soon enough. I then have to put the gear in park and turn the key off for it to disengage.
I cant understand what is going on. All the tires are same (Walmart liberators 235-75/15). Has this happened to anybody else? I need all the help I can get. Thanks.

I hate my Rodeo just being in the Wal-Mart parking lot when I get oil, there is no way I would let those chumps work on it.

The range selector poping out of 4-hi indicates major driveline bind. It's a built-in pressure relief of sorts. Typical cause of this on the 1998+ is a difference in tire circumference. Go back to where you got the tires, explain the situation and have the tires checked. I bet one of those tires is mismarked, defective, or an odd size accidentally put on.

Thank you for your prompt reply. Even though all four tires are liberators, the treads are diferent on two of the tires. I will give them a call tomorrow. Thanks

There's your problem! Hard to beleive those knuckle-heads would go ahead and install a mis-matched set on a 4x4! Major no-no.

I'd request - if possible (if they still have your old tires) to get your money back, and go to an actual tire store, i.e. Discount tire, BigO, even Sears will fair you MUCH better.

I wont let sears touch my vehicles again. They warped my brakes on my mitsu using torque sticks to put the wheels on, after I told them not to. Then I spent 2 hrs arguing with them over it. Wasnt real impressed with the tires either (sears own brand, I'm cheap hehe). I like tires plus, they seem to do a good job and will do a free alignment check if you want. Plus they carry dayton timberline tires which are pretty cheap and are good tires.

I had the same problem with my 01 Rodeo 4WD. When I bought it they had bridgestones on the back and firestones on the front that were the same size, but a slightly different circumference. I had to actually turn the wheels to get the 4WD to engage while moving. I replaced them with a set of Cooper Discoverer AT's from Tire World. I paid just under 5 hundo and have had them for almost 2 years. Great tires. They wear really well and handle snow and dirt like a champ. The only thing I would put on besides the Coopers would be BFG's if I ever found them on sale for the same price as the Coopers!

. I tried a set of coopers years ago. It's the only brand of tire (truck or car) I've bought since. You get alot of tire for the money with cooper & they pretty much are only sold & installed by good shops.

Good to hear about the Coopers. I went out wheelin a couple weeks back and found a steep slope that I never thought I would make. It was rutted out and nasty! I dropped my rodeo into 4L and crawled all the way up to the top with spinning a tire! Then had to back down! I love those tires.

Just a reminder, 4hi is not for pavement of any type, even wet pavement. Only in low traction conditions like snow, mud, or dirt/rock trails should you be using 4hi or 4low. Otherwise, you will bind up the drivetrain and do very bad things to very expensive parts.

Thanks for all the replies. It was the difference in tire circumference that was making the 4wd gear pop off. What happened was, Michelin makes the liberators now, not Uniroyal, but when the mechanics put in the tires in my truck they had mismatched the Uniroyal liberators and Michelin liberators. Don't get me wrong, I like these liberators. They run nice and quiet and for $56.83 a pop you cant go wrong. Somebody had used these tires before and they had liked it so i wanted to give it a try.
