Differential Rebuild Tip

[jim-d-amelio]

I just finished a complete rebuild of my TR4’s differential. The
ring/pinion mesh pattern is critical for diff longevity, so I wanted it
to be perfect. Usually engineer’s blue (also known as machinist’s dye,
etc) is used, but proved unsatisfactory, since it’s dark on a darker
surface. However, white lithium grease proved to be perfect; apply it
with a flux brush (or other small, flat brush) for even distribution
across both sides of half a dozen teeth. The mesh pattern is clearly
visible and easily photographed for your car’s build log. Courtesy of Tom Wiencek
