Possible driveshaft vibration

**tomt41** · 12-05-2002, 12:46 PM

Im just wondering if anyone else has felt the low level vibtration at around 70. I cant tell if its tranny, driveshaft or whatever. Just doesnt sound smooth- Very similiar to a driveshaft inbalance I found on one of my Chevelles. Ive heard , I believe on this site, that there is a driveshaft issue with the 03MM. Any ideas?

I know what you're talking about... Went away when I installed my DynoTech driveshaft from Reinhart...

I haven't noticed any vibration cruising at 70 - or 80 for that matter - or, well - you get the idea!

It's not something I've noticed.

Logan, How much was the drive shaft ?

You think LM will warranty it? try- I'll tell them it needs a Dyno Tech , eh- sounds like a plan- yeah sure!-Thanks for the info-

I cruise at 70+ rather regular, haven't noticed anything...yet. Been up to 125, nothing. What's happening here? I recall drive shaft vibtation from '70 something Chevy products too, noticed it first in the mirrors, but I can't see LM letting this car out (with all these performance features) without considering a proper drive shaft. has anyone checked to see what comes stock?

Smooth as glass for me cruising between 80 and 100. Haven't been over 100 though, so I can't speak about vibration at high speeds.

No vibration at any speed up to 105 mph.

**Mikeenh** · 12-05-2002, 06:02 PM

Didn't notice any vibration when it shifted from third to fourth @ 142 MPH

Love that chip.

Little vibration at 123MPH,but smooth otherwise.

How'd you get 123MPH chapel? I thought they were governed at 117?

I think he's got the chip or else his speedo is off.

No vibration noted to 125 mph.

I think if your at WOT with OD off, you can hit 120+, but that would be about it.
