1st Gen Newbie-Central FL- Need Inside Fuse Box Diagram

Sure it's not 5.29 gears?

 

Any chance he included the front cv axles ??

 

On the older trucks it has to work different. I have no ABS and no wheel speed sensors from factory. Although maybe the ABS trucks require the wheel speed sensors to work to make cruise work.

 

No it's 429 gears but I haven't looked to be 100. No I have to get the cv axles. What does the front have to be upgraded to before I can add them? Thank yall.

 

Hey Nick-This had no ABS from the factory as far as I can tell as well.

 

We have the sensor in the transmission that tells the speedo how fast we're moving. That's why the yellow box thing is made more for the 4spd trans.

Put a line on your tire and one on the driveshaft. Jack the rear up and spin the tire one revolution and see how many times the driveshaft goes around. That'll get you any idea of what you got.

For 4wd to work you'll need a 4.29 in the front as well, or replace both with a known set, like 4.88. You'll probably have to ditch the lift as well.

 

Much Obliged bmf. I appreciate the intell. I had a feeling that was the case. Is there any major advantage or disadvantage between the 4.29 or 4.88 on the 2001 Tundras? The previous owner switched out the rear end with a newer model Tundra for the 4.29 rear end.

 

Available factory rear gear ratios are as below. When you say newer, I'm assuming they haven't swapped the whole rear end for a 2nd gen unit. Doesn't appear that's the case. So I'm guessing it's a 4.30 out of V6?

2000-2003
3.91 - V8, 4x4, auto trans
3.92 - V8, 4x2, auto trans
4.08 - V6, 4x2, auto trans or manual trans
4.10 - V6, 4x4, manual trans
4.30 - V6, 4x4, auto trans

2004, Regular Cab or Access Cab
3.91 - V8, 4x4, auto trans
3.92 - V8, 4x2, auto trans
4.08 - V6, 4x2, auto trans or manual trans
4.10 - V6, 4x4, manual trans
4.30 - V6, 4x4, auto trans

2004, Double Cab
4.08 - V8, 4x2, auto trans
4.10 - V8, 4x4, auto trans

2005-2006
3.77 - V6, 4x2, auto trans
3.91 - V8, 4x4, auto trans
3.92 - V8, 4x2, auto trans
4.08 - V6, 4x2, manual trans

 

Huh, I doubt they swapped the axles in, is the rear using the entire newer Tundra ass-end with 5-lug axles, or are they using adapters to adapt back to 6 in the rear, or did they just swap the guts over?

 

Wow KNABORES
Thats amazing feed. Thank you. I really appreciate you guys. I'm at Dmv right now. I will check when home from work.
I appreciate yall patience with me. I know I'm not the brightest person and probably come across bent with all this lingo. I find out what's up from a mechanic friend what's going on soon enough. I'm honestly not sure if it's 429 or 430 ir if the entire rear was swapped out right now but the tire rotation to drive shaft rotation instructions is awesome. Thanks again guys. I really love these trucks and i am eager to learn.

 

it has 2005 Tundra front disc brake with slotted rotors-
2003 Tundra transmission-
and the rear end chunk is 4.30 and the front end chunk is 4.29 or vice versa. Previous owner has to log through his log book. All the hood fuses weren't blown. I need glasses really bad. Thank yall....

 

Dirty Dodge style. Gross.

 

With 11" of lift and 35's I would expect 4.88's or 5.29's to be installed. IF they did a gear install and not just a 3rd member swap.

But a 3rd member with 4.30's is definitely something they could have grabbed from a junkyard and threw in.

If the front is stock/original it's probably 3.91, could be 4.10's if they did an 04 DC or Sequoia front diff swap.


In any case, IF you decide to part with them, I'd be interested in the 4.30's




P.S. I only say this again, because from what I recall no one has made a 4.29 gear set in our differential size.

 

Hey Assassin-If I part with 4.30's I will let you know. thx alot Man. I appreciate the help. Im here to learn. I could care less what any here thinks of my truck. Look behind you.

 

No worries. Just don't want to steer you wrong.


If you don't have a reliable shop to do gears, east coast gear will sell a complete front diff and ship to you. If you feel comfortable tackling changing the front diff out.

 

Right on. That's awesome to know. I'll let you know sometime next week. I gotta get it to friend of mine first. Thanks alot Man.

 

Hey Man,
I am going to get OEM Reman CV axles for the front to connect my 4wd. My question is I have a Rear Gear of 4.30 from a T100 and the front is the original 3.91. Will there be any issue connecting it? Is the Gear Ratios front to rear close enough to Not have issues? I appreciate your time and help.
God Bless

 

It needs to be the exact same ratio or you'll get massive tire scrub.

 

thank you Sir. Would I be better off changing the front to 4.30 or the rear to 3.91? Or any other combination. I want to do whats best for the truck. Its got 202K on the clock and runs awesome. I just did Valve gaskets, plugs, rack and pinion { was cracked}, fuel filter and some other stuff. I really want to hook up my 4wd as there are no axles in there right now. I am grateful for yalls help and input. If there any good methods to source chunks let me know. Im in central fl but always up for a trip if necessary.

 

With those big ole wheels and tires I'd say 4.56 or 4.88 if you can't find a 4.30 to match. Good job on the upkeep too.

 

thanks Man. Is it a major disadvantage to put 4.30 gears in the front to match the rear if I can find them? Does it make that much of a difference with 4.56 or 4.88, or 5.29 gears in the front and rear on a truck like this? Sounds expensive to find 5.29 gears for front and back but I will ultimately do whats best. I am here for advice and suggestions from yall who know what your talking about and also whats the best route to source 4.88, 5.29 gears. Alot of Junk yards around me.
assassin10000 are you still interested in my 4.30 gears if I do change things around?

God Bless

 

I'm on 33s and want to go up to 4.56s due to the decrease in performance. A lot of people on here run 4.88s with 33s. The ones who do have 35s tend to run 4.88s. I'd say if you can find a 4.30 for the right price go fo it. If nothing else you can go up later and sell the 4.30s on here to recoup some cost.

 

its going to be expensive to change the front and rear gears to 4.88 or 5.29 but if thats what is necessary than I will save up for it. Right now it runs 70mph on the highway in 2WD at 2800 RPMs with 4.30 rear gear if that means anything. Do you happen to know what size I search for with the front and rear ends. I have 2001 Tundra AC V8 4.7 4WD.

 

I guess Im already on Plan B because aint nobody have 4.30 gear in a 7.5 clam shell for the front to match the rear 4.30 gearing. Anyone know of any for sale?

 

^ this. Needs to be the same ratio.

4.88 min or 5.29's for 35's

I definitely am but I doubt you have 4.3's.

East coast gear could build a diff with 4.30's if you want to go that route.

If you're at 2800rpms at 70mph (gps) you definitely don't have 4.30's if you're on 35's

 

I really appreciate your feedback. Im going off what the guy I bought truck from told me. He said the rear came out a T100 and was 4.30. Did they make 5.29 gears for a T100? It definitely revs like mad at 70+-75mph close to 3000 or a lil more RPMs. Maybe the speedometer is jacked. I will have to drive it on highway with my phones gps. I think it was close if I recall correctly. I drive it 12 hours home. The truck has been at my mechanics house for the last 2 weeks. I still need rear bearings and rear cylinders. I wanted to buy the front CV axles to get the 4wd going and here I am. I spoke to Brandon today from East Coast gear and he seemed to think 4.88 front and rear is good but its expensive if they build it. Right now I live in Florida and there aint no hills etc but regardless i want truck dialed in. Would that rpm chart be any different in regards I have a 2003 Transmission installed instead of a stock 2001 tundra transmission. Thanks for your time Man...

 

GPS is the best bet for an accurate mph. Obd2 reader for true rpm. Measure tire height using a piece of 2x4 across top of the tire for actual diameter.

Yes, they made lots of gear options for the 8/8.4". You can mix and match parts and make things work sometimes.

Note: If it truly is a t100 rear diff you may need an adapter flange if you have new 3rd members to swap yourself. You'll have to check flange bolt pattern and spline size.


Yes, the .705 is the o/d ratio for the 00-04 a430 4 speed trans. The 05-06 have a .716 ratio iirc.

 

thanks again Man. Ill drive over there today and measure. The tires seem huge. I apologize in advance for being green. If the truck had a 4.30 rear end would it seem underpowered? Note: If it truly is a t100 rear diff you may need an adapter flange if you have new 3rd members to swap yourself. You'll have to check flange bolt pattern and spline size. Ill take some picture of the rear today. It drives like it can go up a tree and it wont go faster than 75 mph on the highway without major stress. Im sure the guy was told they were 4.30 gears from the junkyard but now I question it. While I got you 2 more questions. Does it make a major difference to get rear diiff lock if I go that route? Its like 600 bucks more money. Also I was thinking of cutting the 2 cats out and running straight pipe. It has a flow master now and sounds good but can always be better. Would it make of us a difference. I am grateful for your time and help. Means alot to me.

 

Have you tried this yet? It'll get you close to seeing what size gears you have. I was thinking 70 @2800 sounds a bit high, but with 35s you were probably closer to 80. Like @assassin10000 said, GPS will give you a better idea of your speed. A diff lock wouldn't be a bad idea, but only if you do moderate offroading, but the lunchbox locker for $600 is kinda iffy. Lastly, don't straight pipe your truck. It will sound like dog shit, be way too loud, and everyone around you, including your neighbors, will fucking hate you. Pretty sure Jesus would hate you too.

 

I wanted to cut the 2 cats off which would only be about 18 inches of straight pipe added to replace where the cats were than into the flow master. I did it to a work van many years ago and it was bad ass loud not dog shit loud.
