I have a 1996 Toyota Tacoma LX Reg Cab V6 5sp 4x4 with 31x10.50 tires. The truck was a running raped aped top speed was 85 MPH. I was involved in an accident and the body shop pirated my parts. It runs like crap now. I jacked up rear of truck, in nuetral, brake off and spun tire, both tires turned, had friend hold one tire while I spun the other one 1 complete turn, the drive shaft rotated 2 and 3/4 turns which I think there is a 2:73 gear in it now.The code on door says B03a R150. Which is 8" ring gear, 4:10 gears, 2 Pinion open. It does have the in cab Differential button which I think is an electric locker.

My question is this, getting ready to spend $1,200.00 to redo the gears in it in hopes of making it like it was. So have considered 4:10, 4:56, 0r 4:88 not sure which will give me the performance I want. It was quick off the line would run nose to nose with older 5.0 Mustangs and lose by a few inches in a quarter mile, climbed hills really well, and top speed was 85 MPH.

I could kick myself for not finding out the previous set up. Now trying to set it up as before. So any input as to the gears, axles, tranny to give the performance would be helpful. Is it possible the factory 4:10 gearing gave that performance? Also are there chip upgrades that may have been responsible for the performance?

its a reg cab v6... you have 190 horse in a truck that weighs absolutely nothing. even with stock gears, 31x10.50s you should be able to roast your one power wheel...

I hope you're refering to the older carbureted 5.0s from 79-83/84. because theres no way you're running against the EFI 5.0, especially the 87-93 which makes 235 hp and 280 torque.

you should spend that money to find out whats wrong with it. theres nothing wrong with the rear end

Will Holden

No it is a fuel injected V6, just spent $3,300.00 on motor, it runs great lots of power, just no torque to the back wheels, that why I suspect the gears were swapped out. Will know Monday for sure when Mechanic takes it apart. Just not sure what to install back in it? yeah, it was the older mustangs not the EFI models, just all I have to go on. Just loved the truck had it since 2000 picked it up with 56,000 k on it. It has 244,000 on it now and thought about buying a newer one, then decided to just spend money on this instead of a truck payment. How does the 4:88 gearing perform compared to 4:56 or 4:10 with the 31x10.50 tires?

If you have an e-locker, then you do not have a 2 pinion rear end, all the e-lockers came with a 4 pinion rear end

Will Holden

Top end rebuilt, new clutch, throw out bearing, pressure plate, new fly wheel, slave cylinder, master brake cylinder, new slide pulley up front, new bearings on ac as well, new rear main seal and new exhaust love the flow master, K&N airflow system,new linkage for the sway bar, new HD bilstien shocks.Have run Amsoil products in it since I've owned it.....now to the new gearing for the rear and she should be right I hope....

Will Holden

yeah saw that about the E-Locker only with 4 pinion rear end, data plate is now missing off rear and metal plate under hood as well, just went by the code B03A R150 on the door jam sticker, thought it should have an R150F transmission as well. Can you be helpful about the gearing?

was your truck in a chop shop? what does body work have to do with differentials?

I run 4:88 gearing on 31" and 33" tires and I have found that perrformance is great on either size. All around street performance is best with the 31" tires. The 33" tires perform better on the expressway at high speed 75-85 MPH.

Will Holden

dealership body shop....why they swapped out my rear not sure but they did....just trying to figure out what to put back in it....think there's a 2:73 in now hoping new gears will give me back original torque, just not sure what gear ratio to go with, 4:10, 4:30, 4:56, 4:88....

Will Holden

So your top speed is 85 mph with the 4:88 gears on 31x10.5 tires? That's all my truck would do before but I loved the performance. 1st, 2nd, 3rd gears would tach out quick and you would have to shifted real quick. Was great from a dead stop the 1st gear really had the tires bite when you took off. Does that sound like your truck with the 4:88 rear?

mokai

I would just go back to that shop and find out what the hell they did to your truck ?

Will Holden

wish it was that simple...hard to prove data plate off rear gone....no just trying to figure out what was in there and replace...in the deep south and they are buddies with the local police.....best thing is just buy the gears and move on....

What kind of damage was done in your crash??

It makes no sense was there severe drive line damage to cause the need to replace both the front and rear differentials??

Why go to all that much work to steal something with that many miles??

2.73 (no such gear set that I have found) or 3.73? you had better hope that if they stole your rear end gears they stole the front too or the first time you are in 4WD your are gonna bind up like crazy.

show pics of this button you are referring to..

Yeah this whole dealership body shop stealing your gears does not add up. Did you check to see if they took the front too? did they swap out your tires and brakes too?

suncomb1

85 MPH is not my top speed it is what I run at on the expressways and interstates sometimes. My speedometer runs at half speed (via conversion gear setup) so I won't break the speedometer or cable anymore. I have no idea what my top speed is but I have a lot of RPM left (rev limiter set at 6500 RPM - engine designed for 8500 RPM) when running at 85 MPH.

wth? dataplate?

look, heres how you tell if youre e-locked... look under the rear and see if theres a servo motor sticking out of the third member... also wires going to it... if its got that, you still have your factory crap, you just dont know what youre talking about... i SERIOUSLY doubt that a bodyshop (especially one contracted from a REPUTABLE dealership would risk a lucrative contract over crap like that...

i dont mean to sound rude but it seems like you just dont know what the hell youre talking about... it seems like something isnt right from the motor rebuild...

btw, anything over 4.10s with stock sized tires is just stupid gearing for a 5spd v6... gas mileage will drop significantly and you will have to race the motor to get anything done thereby compromising the rebuild you just did...

Will Holden

I know you find it hard to believe that a body shop would pillage parts off a vehicle, and remove data plates from a rear. Yet that's what happened. I been driving my Toyota for 12 years. I know how it performed. I have till Monday to figure out what gears to put in it. 4:10 is what is on sticker on door jam. Some have suggested the 31 inch tires came with a 4:56 option from the factory. Like I said not sure if what was in there was factory or it was a change out from the first owner since I brought the truck in 2000 when it was 4 years old.

O saw the pics of your truck, super sweet! Hoping to find someone who still has the 3.4 fuel injected V6 motor. Your motor looks like it has seen some serious upgrades! Thanks for your input just the same!

Will know for sure on Monday when it comes apart. The swap was front and back. The 4 wheel mode still works fine. The gear ratio is just completely different, the truck's top end speed is over 110 mph, can do 70 mph in 4th, it's just a dog now. I hate it, all the gears take forever to tack out or red line. Just hoping it is as simple as changing the gear ratio. When I spun 1 back tire 1 full revolution with back end of truck jacked up the drive shaft turned about 2 and 3/4 turns, that was with holding the other tire still. That is why I think a 2:73 was put in it. Unless the truck had some super chip in it. The change in the truck is no torque from the back tires. Just looking for input to help decide what gears to go with a 4:10 or 4:56 seems to be the options with the 31x10.5 tires I plan on keeping on there. The truck was a screaming raped ape off the line before.

Was a small wreck , slide in to another car cause of gravel and bald tires. left front panel needed replacing. took about 5 weeks to get my truck back.

I've never driven a "raped ape" before. Sounds angry. I doubt your gears were touched. Pull the diff and count the teeth on the rig and pinion, then divide. It's the best way to know whats in there. 41/10, 43/10, 41/9, etc.

Will Holden

Willing to bet there was a V6 Turbo differential in it originally. Took pics of housing on it now.Will know for sure on Monday.Glad no one believes me but there are unscrupulous people and mechanics in this world. Like I said this was a special rear set up ...out of this world. Whatever it was it's gone now! Was just trying to figure out what it was and replace it! Thanks for the responses.
