55 mph vibration Posted By: 94junker On: 08-06-2008 @ 08:38:37 Reply | Edit i just recently changed my pads and rotors in my car all the way around i stripped a lug nut in the rear but i put the lug nut back on a lil bit more than hand tight and i cranked the others down nice and hard now all of a sudden at about 50 it starts to vibrate in the steering wheel and at about 55 it gets pretty crazy it pulls to the right hard the car already had existing steering issues it was developing excessive play in the wheel it gets worse when the weather is warmer??? now the brakes are working fine with no more pulsating and they feel really firm but the way the car is acting it seems like the vibration is coming from the front not the back cuz the car doesnt really vibrate its just mostly the wheel but it makes it hard for me to keep it in my lane at like 60 i have the lug nut to replace and i will do it later on when i get outta work if it stops raining but something tells me this vibration isnt goin to go away oh i also want to add that i kinda figured i had a tie rod goin or i needed an alignment cuz when i took the front tire off the inside of the right tire was almost bald and the tire is brand new its only like 2 inches of the very inside but when i jack the car up the tire doesnt wiggle Posted By: jjdynomite

the vibration sounds like its coming from the uneven tire wear. If its pulling that hard to the right get an alignment, and some new get-a-way treads. --  Posted By: vapor On: 08-06-2008 @ 13:13:27 Reply | Top | Edit check to see if your brake calipar is hanging up. see if the wheel gets really hot on a long stright run without using the brakes. rural country road. Posted By: 94junker On: 08-06-2008 @ 13:27:27 Reply | Top | Edit ill see if its hangin up on my ride home ill use the ebrake to stop i dont see why it would be tire wear cuz its really noticable and it never did anything like this before Posted By: 94junker On: 08-07-2008 @ 09:03:32 Reply | Top | Edit i put the new lug nut in last night on my way home the car was squeaking severly i thought it was the back right side the side where i was missing the lug nut but my girl rode with me after i replaced the nut and she said it was the front right so ill check that today i did take off the back caliper and check it but it seems that the stationary side of the pad constantly rubs and the piston side pad is the only one that doesnt constantly rub but idk what to do to fix it Posted By: 94junker On: 08-12-2008 @ 08:43:11 Reply | Top | Edit ok so i took the pads off and looked at them and its definetly the front side that was rubbing but i cant see anything that i can do to fix it i put the pads back in an pushed the caliper over so there was space between the inside pad and rotor but it still rubs and squeaks horribly it squeaks when im takin right turns but not when im taking left turns and it squeaks horrible when im slowing down i tried the e brake and it doenst squeak so its gotta be the front the vibration is only between 50-60 and when i get over 60 it just goes away Posted By: bignick On: 08-13-2008 @ 18:29:10 Reply | Top | Edit Did you turn the new rotors? If not try that. I had a similar problem in the right rear, I had drilled and slotted rotors and the offset was a little off so it would rub on the caliper bracket. Little grinding took my problems away. --  Posted By: 94junker On: 08-14-2008 @ 16:19:02 Reply | Top | Edit for some reason it seems like the rotor is loose cuz when i turn right it rubs but when i turn left it is quiet and when goin straight it is an off and on type of thing Posted By: 94junker On: 08-19-2008 @ 20:57:49 Reply | Top | Edit but if the rotor was offset wouldnt it pulsate when i step on the brake? so i took off the front rotor, looked at the pads for excessive wear and i greased the caliper alignment bolts and the slides with them and i put the anti squeak shit on the back of the pads i was almost sure it was the front right side i know for a fact its the right side but now that i did that it still squeaks horribly and vibrates just like it did before im thinkin i messed up my wheel bearing when taking the rotor off i did hit it with a 3lb hammer from the backside and i sprayed PB blaster all over the rotor Posted By: 94junker On: 08-27-2008 @ 09:23:04 Reply | Top | Edit what are the chances that i killed my wheel bearing? Posted By: Formula93_350 On: 08-28-2008 @ 14:18:43 Reply | Top | Edit dude im having the same problem. i even hit mine with a hammer (thats when the trouble started), i had to change out wheek studs. i hve yet to figure out the prblem. i ended up just living with it. if you figure it out, please let me know, is the most annoying problem ever. -- 93 Firebird Formula LT1, K&N FIPK, Straight pipes, 1.6 RRs(soon) [IMG]http://i2.photobucket.com/albums/y9/smartpatrol9/FORMULA_001.jpg[/IMG] Posted By: 94junker On: 08-28-2008 @ 14:49:29 Reply | Top | Edit ive taken apart the front caliper and greased the slide pins and ive narrowed down the squeaking to the rear right rotor but idk if thats the source of the vibration the rotor isnt out of round as far as i can tell i think hitting the stud out with a 3lb hammer may have messed the bearings up but im not 100% sure it only vibrates from 50-60 and anything over or under it is fine Posted By: hot_red_z28 On: 08-28-2008 @ 18:30:04 Reply | Top | Edit Given that your tire is wearing away prematurely on one side, I would put my money on an alignment problem... It's entirely possible that the vibration is from the tires trying to fight each other, either from too much toe-in or too much toe-out... Sometimes common speed vibrations can also be caused by an out of balance driveshaft... The alignments are not very expensive though... And certainly less so than buying new tires all the time... -- '88 Chrysler Conquest TSI - 383 LT1 Swap In Progress  '06 Silverado 2500HD LT 4X4 Crew - LBZ 6.6 Duramax

The upper ball joints where shot and causing the suspension to sort of "collapse" inward causeing the inside of the tire to wear and become out-of round. Just think of it like a shopping cart wheel that wobbles around due to the (-) caster/camber. --
