What is the noise? If it's whining under deceleration then the problem is likely a pinion bearing that has gone, but it can be anything really.

The direct answer to your question is no, here's why:
A car without traction control has three channel ABS with the sensor in the diff.
A car with traction control has four channel ABS with sensors at both rear wheels.
The brake lines are different also.

You need to find a three channel rear and swap it in. It'll have an electrical plug in the top of the housing.
You'll also need to match your ratio.
