INFO: STEERING WHEEL VIBRATIONS

[GSpeed]

This is a follow up to my previous post regarding "shudder/vibration upon acceleration". I've sice replaced the stock rotors, which were warped, with Powerslot rotors and Axxis brake pads. I still noticed vibration! Soon after, I installed 17" wheels from 2006 Eclipse with new tires(balenced). I'm still noticing shudder when accelerating from stop! I don't get it! I've heard similiar problems experianced by other owners. Some causes thought to be the problem (car pulling to one side, vibrations) were; faulty caliper supports, defective calipers, warped OEM rotors, off center steering wheel, excessive play in front stabilizer link joint(MR333763) due to inferior quality of plastic socket in joint, replacing transaxle shafts,
repacking wheel berings, torque converter (replacing trans fluid), loose lug nuts. It seems brake problems and suspension problems are verrry common with the 8th gen V6, as is Mitsubishi's failure to find the cause!

Have your control arms and control arm bushings inspected.

RedGalant2k1, that's my next move! Didn't think I would need to since the vehicle (02 ES-V6) has 24,800 miles! I forgot to mention that I had Energy Suspension front (5.3127 ) and rear (5.3128) control arm bushings installed about a year ago.(due to no problems, just upgrade).

Just to chip in as I have the same problem (vibration while hard accelerating) and today I found out why: cracked front and rear motormounts. You might want to check those too if you didn't already, just an idea, IDK if that could be it already at 24K

Anyways, I was getting the vibrations too. Steering wheel goes side to side. So I got new tires and that them high speed balanced. the vibrations are gone. but It just feels like at certain speed the steering wheel is bouncing up and down. Any advice? besides replacing the lower control arm bushing?

i dont understand why people dont actually read the thread they are posting on.
REPLACE YOUR CONTROL ARM BUSHINGS!!!!!!

mitsubishiparts.com

p.s. does anyone know the part number for an 01 gtz?

[sinx]

there's two different probs here.. mine vibrates when i accelerate SOMETIMES..

maybe the guy who said he's replacing his breaks, let mek now if it helps..

kinda an old thread..

[jomin1016]

so does anyone know the part # for a 2000 v6 CONTROL ARM BUSHING?
I've got some bad symptoms,....bad vibration under acceleration - at any speed - from stop to whatever....soon as I let off the gas, it's gone...little squeaks while accelerating from stop - although they're probably still there at higher speeds, just not as noticeable....when I put it in gear, with the brakes on, there's a little "click" - followed by the "squeaking" of the passenger side wheel, while accelerating.

I know it's been a while however, wanted to continue documenting upgrades/part replacements. A couple of months ago, the dealership told me I had a broken motor mount. I thought, so that's it! I sent in (4) core mounts to Deyeme racing to have them filled with polyurethane. I figured this would be a good time to upgrade all (4) mounts. I've since had them installed and noticed an improvement regarding steering vibrations. I will note however, due to the polyurethane be stiffer over the OEM mounts, when starting the car, it vibrates much more than before. This only occurs upon start up. While driving, there is no additional vibrations due to the stiffer mounts. I've read some posts where members(Club 3g) had much more vibrations due to the Deyeme mounts. Most vehicles with standard transmission expereinced this.

yeah, i've been having this problem for about 7 months! i thought it was a warp too, i still need to get it looked at

I've been having similar problems with the vibration in the steering wheel for over a year. (only at high speeds, and it seems to vary at certain speeds) Bought brand new Z rated tires and while having an alignment done, found out one of my front end tie rods was loose. Had them replace it along with a few other high mileage repairs (some belts) and it fixed 92&#37; of the vibration. I can now cruise at 80 without it shaking me apart. 1 week later I was replacing my brake pads and noticed a sway bar link was MISSING! I've got it on order from Mitz and hope that solves the problem. If not I will try the lower control arms & bushings. I've been riding on drilled and slotted rotors for about 3 years and don't notice any shimmy when braking, but an unbalanced rotor can throw an alignment out just as easily as an unbalanced wheel. I may have that checked next. Replacing the rotors w/ some aftermarkets are a good idea for anyone that doesn't want to constantly have to get their rotors turned. 3 years and still have not had to have them turned. I take my car to a shop that uses 'sticky weights' and a high speed balancing system. Places like Midas/Wal-Mart, not sure about PepBoys, only do a static balance and use the weights that attach to the edge of your rim. That is NOT a good way to balance and usually onyl lasts a few months at best. If you've got custom rims, save your money and take it to a real alignment shop for proper balancing. NOTE for White26, I would go with carbon metallic pads as appose to the ceramics. You'll get much better stopping power with the slotted rotors vs. ceramics plus I just repalced mine after 3 years of use and they still had some padding on them. Probably could have gone another year. But if brake dust is an issue, go with the ceramics.

i had the same problem with my steering wheel on a 1999 LS V6, and when i changed my rotors, did a wheel alightment and tire balancing, the vibration was gone for good!!

Update on my vibrations: gone!

Tire balancing on my G was correct but after I swapped my OEM shocks & struts to coilovers and replaced my front right tie rod the shimmy was gone gone. I can do 90 mph with no shimmy and before just getting over 60 mpg gave me periodic but frequent vibrations. Hope this helps somebody.

ahh thanks for the info... i thought it was my rims doing all the shaking, so i put new tires and rims on it, same thing. i was very disappointed. good stuff tho, i'll have to order some new parts.

I have a 2001 galant and my intake manifold broke off just after the throddle body for the second time in just over a year. My car has over 100,000miles and the dealer said within the past year, there have being a increase in this problem with these manifold so thay had to change manufactures.

Thank you for making this a sticky. I can finally prove to them that I'm not crazy about my steering wheel problem. Although it said 2.4L and I have the 3.0L, I still have this problem.
