Well, I just went for a drive and I took her on the highway, and took it up to 120. Then I noticed the whining noise coming from rear of the car. I got off the next exit, pulled in a parking lot, and looked under the car. It didn't look like there were any leaks and that's the only thing that I could tell. On the drive back, the car was making whining noise through the whole drive. It seemed to get louder and more high pitched slightly as the speed increased. There were some whining noise before when I am off the throttle on the highway, but it wasn't loud or anything so I didn't think much of it. My guess is the diff... but what could be wrong with it? I have Kaaz 1.5way LSD on my car btw. But I don't see why that would cause all those noise suddenly... I'm really lost here. I'm probably gonna take her to RX-7 Store next week to get it checked out. Is it ok to drive it or should I get her towed? Help me out here ppl... Thanks in advance.

 

call rx-7 store....

how many miles are on it?

did you do the figure 8 thing when you first put it in to set it?

pull the diff plug and add fluif till it runs out the hole just to make sure that its full
could be universal joints too

 

Diff was put in about 3k miles ago... could it be coz of lack of fluid that it's making noise?

 

that'll do it..... But remeber to put the same fluid in it that was put in when it was changed in case the used redline or something like that.

 

Thanks a lot... I'll try refilling it. Anymore ideas?

 

could be a bad wheel bearing.

 

yah I'd say it sounds more like a bad wheel bearing too.

 

If it's wheel bearing, how much would it cost to replace it?

 

Bout 50-65 bucks for just the part
