vibration issue, any ideas

devanwon -> vibration issue, any ideas (1/12/2008 7:20:25 PM)
ok so I have a 95 suburban LS, 1/2 ton, 152k, has a new tranny as of last year everything else is up on maint. so my issue is that I had the stock wheels/tires on it and I upgraded to 22" wheels with a 305/45/22 tires, now I am getting a vibration at 36-42 mph it does not do it before that or after that, It vibrated on acceleration and on deceleration (with or with out brakes). I have had all the tires checked and balanced they are good. What could cause this, any insight would be very much appreciated. looking to try to fix it without taking it in. my wheels do have the hub centric ring installed too. I was thinking ideler arm maybe?? very open to anything and how to check whats sugessted. thanks everyone!!

i had a similar problem with my first suburban and could not figure out the problem either , and after i got rid of it a mechanic told me i should have checked the rubber insert around the centerbearing on the drive shaft, he said the rubber gets worn and the drive shaft can move around in the bushing thus causing a vibration , hope that helps

any other ideas?? I did find the pitman arm sloppy and the center link sloppy too. would this cause a vibration issue???

did u do a front end alignment when u went to the bigger size rims,also need a program upgrade on the comp to check mph is calibrated and it helps the tranny with shift points due to bigger rims being on ,and member everything is controlled by computer so it doesnt know u have bigger rims on it so u might have everything off balance in the system. it needs to be adjusted for bigger size rims.check into this and see what happens mayb this will help with noises and vibrations u r having.also check your tie rods for wear these go faster with wheel upgrades.

Mine vibes a little. I lost a weight on the driveshaft. Rebalance the shaft and all is good. Yours sounds more like front end like southern said. Yes, sloppy pitman and links will do it too. I've seen 4x4's do it when they need the front wheel bearings repacked.

Going to bigger wheels and wider tires like you did, you probably need to install a steering dampener (steering shock). It is extra stress on the front end with those wider tires on there that causes the vibration you are feeling. A steering dampener will hold the vibrations down by absorbing the vibration and "holding" the steering components in place. I would bet this will solve your problem.
