I took the Jeep and got the tires road force balanced on Saturday and did not get to drive it alot over the weekend but yesterday and this morning were HORRIBLE the vibration past 60-120 is so bad it feels like the whole Jeep is going to fall apart and even worse on decelleration, any suggestions or ideas because I went thru the same thing with the truck and never got it resolved. This morning I took it up to 100 MPH and right at about 60 MPH is when it starts but when I was slowing back down and right at about 80 MPH the whole steering wheel and Jeep were shaking BAD could it be the alignment??? There is one step further with the Hunter stuff I can try but doubt it will do any good I dont even want to drive it right now
80's about the magic number in my Mag too, Wade. Force balancing did squat...it's effin' frustrating me so much that I'm thinking about getting aftermarket 20's with new tires. My my 17" SXT winter steelies are smooth as silk on the other hand. Let us know what you discover further!
Well it's one of 3 things: #1 - The place you had your tires balanced at are mouth breathers #2 - One of your tires is out of round or a steel belt shifted both which are not visible #3 - There is a suspension part loose in your front end. Do you feel mostly in the steering wheel? Do you get a wobbling sensation in the car it self? A little more information might help me narrow it down for you.
I had same problem and they rotated tires 180 degrees and re balanced and problem was solved. Im kind shocked that your having problems balancing a performance tire, I always thought mudders and all terains were the only problem. Good luck and let us know
WOW I'm shocked so many people are having problems. Most of my suspension/tires experience comes from lifting trucks where vehicles are more prone to these kind of problems. There's got be a common denominator, and I'm betting it's in the front end. I wish you guys were close to Virginia Beach, VA. my curiosity has peaked.
GCulver was telling me that inside the wheel there is a mark that has to be positioned on top or bottom when mounting the new tire, IDK I need to know the exact procedure on mounting new tires on this beast I know its not just slapping a new tire and and balancing it maybe the original place that put the new tires on did it wrong???? I'm going to check the JeepWk site for correct details and go back to Nissan and have them take the tires off the rim and start over, use the other LFI Hunter machine that puts about 1400lbs of pressure on the wheel when mounted to check for any imperfections
Tire mounting caution: When the tires on mounted on the rim, make sure the dealer knows to align the high runout point mark on the new tire with the low runout point mark on the SRT rim (this information is provided in the Goodyear Product Bulletin for this campaign). The high runout point on the tire will be marked in the upper sidewall with a white dot and either the letter “A” or a “+” or “-“ sign. The low point mark on the rim is marked with an “X” engraved into the dropwell of the rim Okay they did not do this BUT the Toyo tires do not have a mark so now what
figure out exactly what the high runout point of a tire is and then identify it on your unmarked tire. mine have the white dots, i didnt know what theyre for but now i do
Honestly this does not raise any issues in most vehicles, a good balance will make up the difference. Of course it's always good to line up the marked weights but I highly doubt that it will remedy the problem.
I agree with Haedes. I had the vibration at the same speeds, its the magic speed range that everyone with this problem seems to complain about. Granted, my vibration was not as violent as the one you describe. Here is where I agree with #1 above. I had them road forced balanced by someone who did not really know how to use the Hunter machine and/or did not know how to balance a tire. I explained my problem to the service tech at the dealership and he gave me a recommendation on another shop with a Hunter 9700. I took it there and "walla", no vibration at any speed. Did your shop do a static balance? (one row of weights placed toward the center of the width of the wheel) Or, did they balance it with the method that they use two rows of weights (one toward the each edge of the width of the rim)? I was told that it is difficult to static balance these large wheels/tires. Balancing may not be your problem but I do not think you can eliminate it yet. I would add #4 to the list above. Hunter machines have to be recalibrated every so often. If the machine is out of calibration, it could be tough to get the proper balance.
Keep em coming because I'm taking all suggestions back to Nissan. It's a brand new dealership and the Hunter is new so hopefully its good but maybe is too new for their techs to know how to use it
Dang that sucks Wade. Especially since you have brand new tires. My only guess is one of them is not balanced correctly or one of the tires has a defect?
One or both of the tires could have a defect or be so far out of round as to be considered out of spec. The Hunter machine should be able to determine that.
The hunter machines takes like 30 sec to be calibrated, so ask them to check their machine. And MOST definitely ask for a static balance, with sticky weights on close to the outside edge of the wheel and knock on weights on the back of the rims lip. I'm still having a hard time believing that a balance issue would cause such "HORRIBLE" vibrations.... but stranger things have happened.
Hey thanks for the advice as I would have never thought to recalibrate the tire size VIA the Diablo. See I had a service appt this morning at JEEP so I put it back to stock before I pulled into JEEP for service, when I left there I had a 45 minute ride to Clifton to do an Appraisal and not once did it vibrate. I was able to do a gradual 0-80 run, 60-80, 80-120 mixing in nailing it and gradual build up to speed and it was smooth sailing. Now before I left to come back to the office I callked Blown-WK and he suggested chaning the tire size and maybe the settings on the Diablo did not like the differing sizes vs what was stored so I loaded the Diablo and found the tire setting menu and you have 2 choices, either by tire height or you can enter the exact tire size i.e. 275/40-R20 so I was like uuugggh which one do I use so I decided to be exact and entered the tire size then I thought CRAP the front and rears are different size WHICH ONE so I chose the fronts and on my way home did the same test as I did stock on the way to Clifton and it was all smooth. NOW in the morning where this usually rears its ugly head is where I will know if this really helped if not that tells me something about the tires needing to be warmed up???
Wade, Im totally confused by what you and Chris are speaking about lease: How does the Predator have a effect on the wheels, are you saying there was a vib being caused by the driveline and not the wheels ?
