Hammering sound under car !!!!

[LeDevil]

Well this still relates to my driveshaft, I've replaced the Rubber Guibo and my U-joint is fine but I'm getting what sounds like someoen under my car hitting it with a hammer in the tunnel right behind the shifter what else could I be missing? side note it go's away at 40+ mph.

Im guessing this is an auto? If it is, then it probably is a bad transmision, or at least a few bad gears (up to 40mph)

[LeDevil]

Sorry I should have mentioned it's a 5 speed

[Harls]

Only one thought, is your gear linkage between the selector shaft and your gear stick loose?

If you are finding that your gear changes are getting real sloppy it might be something like that.

Happened to me and the link plate was banging against the floor when I gave it some.

just a thought

[LeDevil]

If anyone else is having this issue check the rubber bearing thing in the middle of your drive shaft. That's what was wrong this hole time. So thanks for the help guys

Two question Le Devil:

1) Is that your car in your sig?
2) Is its paintjob a calypso red, or is it just darkness of the picture?

Cus if it is, I am SO freking jelous... I was looked everywhere for that color, but only found brillian red

[LeDevil]

That's my car and as far as I know it's the stock red, I don't know if BMW called it that or not. How would I check?

[325i Phoenix]

Calypso red is a stock color, so is brilliant red. Just depends on the shade of the red. If it's a bright red its brilliant, if its a dark kind of maroonish type of red, it's calypso

[LeDevil]

Oh then it's brilliant red

[325i Phoenix]

Oh. I couldn't really tell, it looked like calypso on the pic
