rear wheel woes

My new rear mt. bike wheel complete with seven-speed freewheel
will not stay seated in my bike. Everytime I get it centered and
locked down with the quick-release lever, it pulls out once I start
peddaling. The wheel also seems to want to pull to one side when I
apply pressure to the QR lever. It has also mangeled both tapered springs.
Granted, I'm not a mechanic, but I've taken off and put back a
many a rear wheel and never had a problem like this. What is the
heck is going on? I'm on my own since the nearest bike shop is 90
miles away. Also, what are the springs for and are they necessary?

wonder if the Quick release is dead. Do you have another one sitting around? probably get one from a friend? WHat I think is that the threads at the other side, the driver side of the QR thingy, are toasted, so no matter how much u tight the QR lever, it will get lose. Get one from a friend for a few minutes.

Thanks.

ps: the springs are there to get the qr centered, if you dont have them not a big deal... again, borrow a qr from a friend for a few minutes.

Are the dropouts misaligned?

Is one end of the axle protruding (or flush) beyond the outside of the drop out? The axle should be a few MM short of being flush.

Edit-
Is this a new wheel or a new bike?
IF just a wheel, you probably are trying to fit a 135 into a 130MM OLD, or 130 into 126MM.

IF a new bike, take it back where you bought it and let them fix it!

Maybe the axle is not centered in the wheel (or is just too long). If it sticks out too much on one side the QR will tighten against it and not the dropout. The exposed threaded portion of the axle must be smaller than the width of the dropout material.

Has someone worked on the wheel (hub) lately?

I see that Bill and I were writing at the same time <g>

A couple of ideas.

1. Like the others have mentioned. If your axle projects beyond the dropout even the tiniest bit, it will prevent the QR from tightening against the dropout.

2. All quick releases aren't created equal. Campy, Shimano and other quick releases that conceal the mechanism are far superior to the ones in which the actual mechanism is esposed.

3. Those little conical springs, the narrow end goes against the axle. If yours are mangled I'm thinking they were installed backwards at some point.
