Need Help With A Noise...
 

I have a 1994 Ford Probe(4cylinder/automatic). My mechanic installed a rebuilt rightside axel the other day. This is the first time I have drove it since I took it back home from the mechanics. I got on the highway and noticed that when I slow down below 50 miles an hour my car from up front makes a loud high pitched shrieking sound. When I slow down below 40 miles an hour in addition to this sound there is a faint what sounds like metal scraping(nothing is hanging down from the car touching the ground). When I go above 50 both sounds stop as well as when I come to a complete stop both sounds stop then too. I am not even sure its the axel, it could be something totally different, but that is the only change I made to it since then. Anyone know what this could be? I have to get to work over the weekend, and the mechanic won't be open again til Monday morning. I am kinda scared to drive it but don't have any other way to get there as my roommate is out of town. Thanks!!

To be on the safe side, it would be best to have someone look at it and at least see if the noise is something serious. If not, then you probably could use it without too much concern until the shop is open on Monday.
