98 cobra rear end noise

My thoughts on rear end service. Most anytime ANY repair work is needed it's best to just rebuild the whole rear end. Reason? The cost of the rebuild kit is so low compared to the labor involved that taking a chance on a re-work is not worth the small savings in parts.

This goes double when dealing with an IRS application. Add to this the need to inspect the outer wheel hub bearings.

So unless you are well experienced in rebuilding rear ends and can tell the difference between a worn bearing and a re-usable one, rebuild the whole thing.
