1934 Ford Roadster Pickup - Suspended With Function & Style

For installing the housing's third member-case studs, Jeff placed the case on carpeted wood blocks on its curved rearend. He installed the Loctite-treated Allen studs first by hand and tightened them with a portable Snap-on impact wrench.

Torco Oil, 85W120 viscosity, totaling 26 pumps went into the case.

Since the Currie Enterprises 3.50:1 geared third member is a T.S.D. Limited Slip unit, compatible with 31-spline axles, a 4-ounce bottle of Ford Racing Additive Friction Modifier was added, bringing the total amount of lubricant in the case to 1.5 quarts. If the differential were standard, 29 pumps of Torco gear oil would have been added in step 8, which equals 1.5 quarts.

Jeff placed the Strange Engineering polished- aluminum case with the Currie T.S.D. Limited Slip third member inside atop the Kugel housing. The pinion yolk is missing in action, since it's being chromed. Also, the gold Grade 8 fasteners will be replaced with polished hardware upon the IRS' final detailing.

Kugel has a drawer in one of its toolboxes dedicated to all the IRS hardware. Jeff dipped inside the hardware candy store for the appropriate fasteners.

Before installing two washers and a nylock on each stud, Jeff used anti-seize on the studs' threads. Especially when attaching stainless steel fasteners to more stainless, this is essential to prevent the nylocks from seizing.

Jeff employed the speed wrench to swiftly tighten the nylocks holding the Currie/Strange assembly firmly in place.

Once the third member and case were in place, the pivot plate was bolted to the bottom of the Kugel housing.

Before moving to the next step in the assembly process, Jeff put the rearend on its literal pivot-plate-attached bottom and confirmed the unit was level.
