Strange vibrations I have a '99 Civic LX 4dr/sdn and noticed a hard vibration felt in the steering wheel. I can be felt driving at high speeds 50+ (not saying its not there at lower speeds, but can be felt at higher speeds). Put on 4 new tires and no change. Tranny checked out ok. Even looked for a bad wheel bearing and nothing. Had front end rebuilt prior to this about 4 years ago so o don't think i have worn bushings or a bad tierod. What could this possibly be? Any and all help is appreciated.

check front end by starting car have someone rock steering back and forth look for any parts that is moving more than others. keep in mind high speed vibration can be tires, wheel bearing, trainning and mounts. have someone follow you and looking at tires for bearing if both drive tires are shaking look at training and steering. good luck

I presume that is miles per hour. If the vibration is felt in the steering wheel, the problem is probably in the front wheels. If the vibration is felt in the seat, check the rear wheels. To check the rear wheels, if it is not posi traction, just jack up one wheel at a time and bring the speed up to half the odometer reading (one wheel turns twice as fast as two wheels). To check the front wheels just rotate to the rear one wheel at a time.

Also check for bent rims and defective universal joints.

If this is happening at around 40 to 50 mph and it goes away when you go faster or slower then those speeds you probably need a wheel balanced. (please rate if this helps any Thank you)

check engine and gear box mountings

This sounds like you need new track rod ends, this would cause free play in the steering, also it could be the bottom suspension arms. the garage should have checked these though! if the wheel is vibrateing then it may need the wheels rebalanced. if it is that you steering will shake at 60mph

I just had the same issue with a 1999 2500HD and the vibration got worse above 50 mph. Problem was resolved with a new driveshaft. Old one (aluminum) was badly out of true and the problem didn't really occur until I had the U joints changed - then bent driveshaft vibration was noticeable. New driveshaft resolved issue.

Front shocks are week

on both my Camrys, i had this problem. You could really notice it when you were driving down the road going 40-60 mph and punch the gas - car would vibrate, let off the gas - vibration stops, punch the gas - car vibrates...... On both, it was the CV joints. It is much easier to just replace the drive axles (with the new cv joints and boots already installed). For my last replacement, i think thy were only around $65 each.

hello have u rotated the tires front to rear then drive and see if u still have the noise and vibration if drive yes while driving slowely turn the steering wheel left to right just a small amount if the noise changes its probably a front wheel bearing if that doesn.t help drive the truck till you get the vibration then let up on the gas pedal does the noise go away if so you might have a bad u_joint but do the tires first how many miles???????
