Never change a running system
194000 mile update
Okay. I now have over 194,000 miles on my Sedona. 3 weeks ago I pulled off the timing covers to replace the timing belt and water pump. This was to be its first replacement. Now, the manual recommends this to be replaced at 60K intervals, but I have always believed that time hurts a vehicle a lot more than miles do. The wear indicators on the timig belt showed no signs of deterioration and the writing on the back of the belt was still very legible. BTW Gates makes Kia's timing belts I did NOT replace it. "If it ain't broke, don't fix it." This is not to say I haven't had other problems, though.
Evidently, Sedonas have an inherant design flaw in there suspension. Specifically the struts and mounts. Annoying vibrations are heard at the least little bump. Sometimes it seems the smaller the bump, the louder the vibration. I know how to fix this: relocation of the strut and mount... but I'm no front-end specialist therefore I don't know where to drill the holes to do this. Any clues anybody?
Also, the front right wheel bearing separated this past weekend. I replaced it twice in one day only to have both of them separate within the first 4 miles of the test drive. So I was thinking I just wasn't holding my mouth right or something. I took my hub assembly to one of the few mechanics I trust that has a press to replace the bearing for a third time and he pointed out significant wear on the back end of the studded hub spindle. This is the part that the CV shaft slides into. The CV and the spindle turn at a 1:1 ratio because of the splines that interlock to turn the wheel. How can there be wear there? Whatever the cause, I am now going to have to replace the spindle. A local junkyard has a whole hub assembly for $75. I think that's how I'll go, because Kia's list price is $96 just for that spindle.
194,000 miles and the only other problems I've had have been only brakes. Aftermarket rotors warp very easily. The rear (drum) brakes lasted till 180K, but the aftermarket lists 789 as the part number for the shoes. Nope.... not right! I had to order them from Kia. $79 list on those jewels. $63 if you qualify for a discount, but still steep for shoes.
SeaFoam has been the cleaner of choice for the inside of the motor. I still have the original spark plugs!!
