Shakes or Wobbles problem
2003 Kia Sedona 6 cyl Front Wheel Drive Automatic

I get a very rough vibration around 40 -45 mph. It happens on heavy acceleration or when I am going up hills. The wheels are balanced and this condition doesn't seem to exist while driving on the highway. Could it be the motor mounts? If so which ones should I look for to be damaged.

It could be a motor mount, bent rim. If you rotate the tires, does the vibration change? Where do you feel it more, the steering or the seat?

OK, I found that the front driver's side motor mount was broken as well as the back drivers side (motor/Trans mount) were broken. I replaced these and now the vibration is better, but still exists. Should I replace the top, front, passenger side motor mount as well. How can I check if this one is broken, you cant see the rubber like the others.

Chances are if you had two broken ones, then at least the rubber mounts on the others are bad.

I replaced all three of the motor mounts. Two out of the three were visibly broken. The vibration was better but still existed. By now I was thinking bad tranny or torque converter. But I had to try one more thing first. I bought a left hand side cv half shaft and replaced that. The vibration wasn't so bad but still was there. Then I replaced the Right hand side cv hald shaft. Finally the vibration is gone. The inner side of the cv joint was very loose on both sides. The problem now has been solved. I wonder if the broken motor mounts contributed to the wear on the CV joints.

Glad it is fixed, and yes, the mounts could have contributed to the problem.

Let us know if you have questions in the future.

I have had this exact performance scenario with my 2010 Kia Sedona. I've just put the 3rd axel on it in past 10 months. I do put a LOT of mileage on my vans, and they are art cars (award winning, too) so they get whatEVER they want, and I do drive pretty gently, and never over speed limit. My Kia is Freedom Van, now has 169,000 miles (was 5 years old last month). Liberty Van is a 2004 Nissan Quest, with 410,000+ miles on it. Pics of both are at www. Libertyvan. Com.

Last May, paid Martin KIA in Bowling Green, KY about 1,200 for all new motor mounts (because of the vibration), also had new axel put on driver's side of KIA just before Memorial Day (by a local shop), then took trip to Washington DC for the holiday weekend. The new axel performed poorly (noise, shaky in front). When I got home, paid Martin KIA of Bowling Green, KY about 1,200 *(AGAIN) to replace both front axles and bearings, I usually TELL them I run the wheels off my vans, and to fix WHATEVER they need (both my vans are spoiled rotten, they get whatever they want! (This KIA got new shocks and struts at 60,000). Travel all over the USA, usually by myself (and often with dogs)- HATE to get stuck. She had about 124,000 miles then. Last Wed, while stopping for a light (in a 25mph downtown area), heard a pop noise from left front. Didn't feel anything off, and didn't see anything, so made it home (was about 100 miles). Stopped and checked as best I could a couple of times as it just did not feel right, but couldn't find anything. Had been driving through construction, so figured it was just the road. Next day or two, was hauling dogs to and from groomer all week - I raise Afghan Hound show dogs, and kept hearing occasional clicking or popping noises. KNEW something not right, so Friday afternoon, took to my local shop. They checked, thought a tie rod might be loose, so I made apt. To bring in Mon. Then, (they told me ok to drive it), ran 20 miles at 70 up parkway to go to Walmart (I live in middle of nowhere, other reason I rack up so many miles), just pulled onto the on ramp, slowed down, when heard loud pop, suddenly steering wheel was jerking back and forth like huge flat tire. But I knew it was not a tire - they were brand new, about 10 days old. I hit the emergency flashers, and coasted it at 5mph about a block to a gas station. Had to call for a tow - the driver's side axel BROKE in pieces. JUST brought home from shop with new axel. Is there some reason this thing eats axels?
