This cover is not your typical cap that you just weld over the thin stock housing. With our cover you completely remove the factory cap (a quick job with a cut off wheel) and weld a laser cut and bent ¼" plate steel cover in its place. This is a little more work but the payoff is worth it for the total coverage and increased oil capacity. Covers ship fully welded with a large fill plug so all you have to do is prep your axle and weld it on! The fill plug uses a 9/16 allen wrench. This is also the most economical fix for a rusted leaking Toyota rear axle. This cover looks slightly different than the factory cover, but rest assured it will fit the applications listed below.
