Rear Grinding Noise on Takeoff

svxthc · #1 06-10-2005, 05:57 PM

It seems after I start the car and accelerate there is this click/grinding sound coming from the rear lower end, almost sounding like the exhaust is making the noise. I let the car warm up for roughly a minute and I still get this abbreviated sound coming from the back of the car for the first quarter mile of the ride whenever I move from a stop. Any ideas what this could be? It's nothing major and it only happens it seems before the car has warmed up. I was just wondering if any of you had experienced anything similar in your svx!

Could be the differential.

Are you sure it's not the exhaust?

One way to find out is to rev the engine a little in park while it's cold. If it is the exhaust it won't matter whether it's moving or not. If it's a drivetrain component chances are it won't make the noise parked.

Like a dummy I revved it in park like 5 seconds after starting it up before it had the chance to heat up and it started smoking out of the exhaust, not doing that again.

How high did you go? Simulating actual driving would only require you going up to about 2-2.5k.
If you drive when it's cold like that it does the same thing...
Did you listen for the noise?
