Free Wheel Manual Hubs Conversion Kit

the oem 1st gen Tacoma left driver side part number ?

 

Do not know that off the top of my head. Sorry.

 

what year ext. would i look up for the oem? I am 66 and doing the work myself its a challenge

 

I think ,I found the oem part 43502-35160 ok now whats is the bearing i need part number please

 

the hub assembly was all one piece in the kit so how do I separate the 2 pieces? is that why the outer hub is treaded at the end to screw together? than the enter piece has the bearing that has to be pressed out than new pressed back in?

 

He uses a 1st gen tacoma hub and presses it into a 2nd gen wheel bearing. You would be better off buying a new bearing with the 4bolt flange, tough to press the hub out of the bearing without killing the bearing. There is a specific order things need to go back together, if i recall correctly the hub bolts and a seal need to be installed prior to pressing the hub into the bearing, then you need the proper 4pin tool to torque the hub. Im on the road for a few days, if the seller won’t help you out I can help out some more when I get back.

 

Please excuse my ignorance with the 2nd gen Tacoma hubs. My xrunner isn't 4x4.

I had an 87 4 runner many years ago with auto hubs that would try to enngage/disengage first drive when cold. As I recall when I converted to manual locking hubs (Warn) it was simply the 6 Allen bolts and swap. That was 25 years ago, so...

I'm interested because my son has a 6 speed 08 Tacoma 4x4. He's looking into the auto to manual 2/4 wd high/low conversion as he's had the typical 4wd engagement issues in the transmission itself.

I haven't read through all 22 pages yet (I will when time allows) but I'm surprised this manual hub conversion seems to be a bit involved? Are gen2 front axles solid axle full time?

 

Same concepts different systems. Toyota had manual hubs and also had auto hubs prior to 95. Then came Auto Disconnecting Differential and Manual hubs again but different outer stub spline counts. Second Gen all have the ADD setup and need a special outer stub CV to create a manual hub setup.

 

The 2nd gen tacoma, 4runner, and fj Cruiser are all based on the same/similar platform and use from the factory sealed "auto" hubs ( basically do not disconnect) and use an electronic actuator stub shaft right of the differential to "engage" 4x4 operations across the front axle. It is not a solid axle as the 70s and 80s were, but has a solid diff and stub shaft connected to double wishbone suspension and transmits the drive motion to the outer hub via CV shafts. There is one or 2 people that make a manual hub conversion here on the forum that has mixed reviews and one or 2 companies that have massively expensive long travel front suspension set ups and options to change front drive hubs to outer u joint style but still an independent front set up unless you go the solid axle swap route which is a whole other discussion and thread.

 

Yeah, I've had a few jeeps with straight axles/cluch posi front diffs. It used a vacuum operated solenoid to slid a sleeve locking/unlocking a single axle. The other axle was a solid 1 piece axle. The drive shaft was full time. Everthing was still always spinning. I guess the only thing this accomplished was to eliminate front wheel bind when turning.

I'm familiar with Ford axles and operations. Although not as simple and cheap to do, freeing up the drive shaft, diff. and axles is beneficial. The parasitic energy consumption/wear from constant, unnecessary spinning dead weight isn't nessasary. I would imagine Toyota's setup was purely cost saving.

 

Yeah, I'd agree that it was more than likely a decision made to make hubs into a fairly "uncomplicated" issue for the masses and also a decision ( whether knowingly or not) towards planned obsolescence knowing this would be a wear item that would cause those of us that wanted to keep our vehicles past the 3-5yr norm an added expense and hassle that helped justify the Neverending cycle of just trading in for the new version... I wish toyota had made it easier or there were an aftermarket solution that made converting to manual locking hubs easier as I'd Def do it.

 

When was the last locking hubs avalible. Was 1st gen the switch over point?
Ford was going over in the late 80's I believe. A friend bought an 89 Range w/ auto hubs. It would unlock in revese condions.

My 87 4runner previously mentioned was origanally auto-crap-tic hubs. The Warn hubs just bolted over and eliminated the intermittant cold lockup in and out sticking? It would violently engage/disengage.

 

With Toyota's front diff disconnect, the passenger CV axle free-wheels. The driver CV axle turns the spider gears, but because the other side is disconnected, the ring & pinion don't turn, and the front drive shaft doesn't turn. Most of the parasitic drag comes from the hypoid ring & pinion gear set, so Toyota's system reaps most of the fuel economy benefits while being significantly more reliable than Ford's vacuum-operated hubs.

 

1995-2000.5 was the only years that the Tacoma was fitted with manual hub options. They can be fitted in anything from a 4Runner or Tacoma from 95-04 with or without ABS setups.

Also Tundra 1st gens

 

05taco4x4,

When will you offer these kits again? If never, would you be willing to share the info so some of us can recreate the kit for ourselves?

 

I had a late 80's? Jeep Cherokee that did the same lock/unlock idea as toyota. Locking 1 axle using a vacuum slider to couple it. If you'd try to turn on pavement when engaged in 4x4, you'd know it!.

 

^Modern Wranglers/Gladiators still have it, but changed to electric actuation like Toyota's:



From what I read, Mopar offers an electrical bypass kit for people upgrading to chromoly axle shafts, bigger axles, and/or manual hubs.

 

hit up sideline hero here on TW, he is still making these kits.

 

Can't find him

 

looks like new LC might come w front manual hubs. I wonder why



me figuring out if these are compatible with 17x8.5 Method 701 bead grip, red CVJ high angle boots, and future compatible with longer travel 934 RCV, and when it becomes worth to just do MarTec SAS which may or may not entail manual hubs
