Re: Torsen front differential anyone?

=D> Congratulations on a successful Zexel Torsen® snow test! The dual-drive differential as engineered by Vernon Gleasman in the 1950's, with its crossed-axis helical gears, is a Chinese puzzle even to depot repairmen. But the Torsen Type 1's behavior under unequal load resistance sold Unionauto AG,...

Re: No spare tire on my dutch doors, what about fuel cans?

:cheers: Thanks for the advance info for modding my M11006 for trailering. I've laid contingency for an upgrade spare-tire winch to handle 40 max # for reserve strength enough for a ø15"x7" ALCOA® rim and LT235/70R15 110Q all-terrain (immediate plans only involve a P215/75R15 100S full-service spare...

Re: 96 Lifted, Locked, AWD, Safari in Tacoma

Down here on the edge of the Central Valley (CA, USA), I've researched a stick-shift retrofit and already decided on upgrade axles; I b...

Re: Safari SLE upgrade-speaker question

Re: Safari SLE upgrade-speaker question

:-k Update: I ran across a brochure PDF from Scosche indicating that the stock speakers are actually ø7" for the front doors and rear Dutch doors. I'll have to measure the screw-holes to see whether ø6.5" or ø6.75" aftermarket speakers will work in terms of solid mounting. The 4"x6" for the D-pillar...

Re: Passenger door, BOTH handles broken. How open?

#-o Sorry to resurrect an old thread, but I found the root cause of the handle breakage: Unfortunately, General Motors committed an execution flaw in the very latch assemblies of the M-body cab doors. Not enough meat on the release pawls to allow for wear. Early 2019, I replaced the outside driver-d...

Re: New aftermarket headlights installed.

HID H4 replacements are only as good as the housings you install them in. If the reflector has poor focus and cut-off, then you will blind oncoming drivers. But if the focus is correct, they can work extremely well. HID's do use a single filament like the halogens, so they can work well if the hous...

For my 1997 M11006's interior relamp-in-progress, I selected the PILOT® IL-194W-1 for five of six map lights (too bad Pilot Automotive hasn't seen fit to manufacture an IL-194R-1, as I wanted one map light red); the PILOT® I...

Safari SLE upgrade-speaker question

I am currently looking over several manufacturers' offerings for upgrade speakers for my 1997 M11006. The 4" x 6" positions in the D-pillars are a known and well-supported size in the automotive aftermarket; but the 6" positions in the cab doors (full-range or multiaxial) and Dutch doors (woofers) a...
