So I have this nagging ongoing issue with my 03. On the freeway going 65-75ish you can feel a very faint vibration in the wheels, gas pedal) and if your leg is resting on the door panel you can feel it too. It comes and goes. It says most of the time. It's not the road as you can feel it on a completely smooth stretch and then other times you can't.
I had new wheels/tires put on it last year. I've had them balanced 3-4 times and it's still there. I have *not* had them road force tested yet. That was going to be next.
I thought this might be converter shudder. I say this because there's a slight whining/bearing noise coming from the area where the TC is. Yep. I took a long pipe and put it right over the trans casing where it meets the block and you can faintly hear it. However, it ONLY happens in park when the car is not in gear. Put the car in gear and it goes away. I had my trans buddy come over last Friday and he said either the TC is going out or there's a bearing there that would war out and cause that (input shaft bearing?). I'd hate to replace the bearing and put the car back together and still have the same issue. I also don't want to replace the TC if I don't have to.
I know what TC shudder feels like. It's nothing like that. It doesn't shake the car like it did on my other one that was having the issue. If I put the car in 3rd on the freeway it's still there. If you let off the gas and just coast it's still there. The RPM's don't "pulsate" when the shaking is going on.
Now I'll throw something else in the mix. Last summer/fall I magically had my passenger side axle nut fall off while driving (yes.. fell off). I have GSX wheels and the center cap kept the nut from flying away. I just pushed the axle back into the hub and torqued down the axle nut with some thread locker. Haven't removed it since. When putting the axle nut back on I noticed the splines were ok but weren't perfect. I do have a spare wheel bearing I can try though. I can't remember but I believe the shudder at 60-70 was there before the axle nut decided to come off.
The other thing I just thought about was I could swap my junky poverty race car tires and put them on the 03 (they're just GP 5 spokes) to see if the vibration goes away on the freeway.
I'm pretty sure I can't hook up my DHP and take off the TCC apply or what not while driving. My friend has an HP tuners and we could try it with that to see if the shuddering goes away.
Forgot to add. I did the typical "jack the car up and do the wheel bearing/ball joint/tie rod" test. Nothing with excessive movement either.
Thoughts/comments/who cares?
