What have you done to your 1st gen Tundra today?

you're on 265/75s correct?

 

Yes. I will be going to 255/80r17s though. Probably a bit of a hit there but debating 4.10s or 4.30s.

 

Just a question, I have the V6 manual trans version of this truck and it comes with 4.10 gears stock. Id like to go to 33 inch tires down the road and from what ive read, it could make my truck more sluggish. Should i regear to 4.56 gears ya think?

By the way, Im thinking of getting 255 85 16 tires.

 

It will help restore some acceleration if you do.

 

Sorry another follow up question. Ya think I should buy the 33's and try them and see if its worth regearing, or would you regear knowing you were going to 33s beforehand?

 

I went with 255/80R17s expecting to want to regear...but after going up in size (and weight) with the tire, the gearing is not that big a deal. I have a much more powerful motor than you, but you do not have a slushbox, so I would try the tires first and see what you think. A front and rear re-gear is not cheap...you are looking at $2-3K depending on what part of the country you are in.

 

Try tires first. No point in doing gears and being unhappy with the results. Only reason I’ll eventually regear with the bigger tires is just to keep it happy towing, but even then I might not if I feel it’s still adequate (plus I’ll be adding power with headers before a regear, probably be more noticeable than regear)

 

I have a set of 4.30 gears from a different Toyota (forgot what it was from) whole rear diff was replaced due to bearing noise, the ring and pinion were fine. So those gears are going into my spare 8.4” diff and getting an trd lsd or trutrac. Down the line of course.

 

Man, I was thinking of regearing to 4.88s. this thing is a dog with the bigger tires. You'd be surprised.

 

lol I’ve got the VVTI and it makes quite the difference. Broader torque curve is noticeable. My 265/75r16s weigh around 80lbs a wheel. So weight is way up from stock.

 

So wheel weights are pretty similar to what I have then, it just comes down to my bigger diameter, and non-vvti and 4 speed auto. I'd love to see a dyne chart of a VVTI 4.7 vs a non-VVTI.

 

I like! what brand are these wheels? Id love to see a pic when you get em on the truck!!

 

Anyone know why LED bulbs all have big heat sinks are some even have fans? LEDs take less to run, run cooler to the touch yet need more heat dissipation.....makes no sense to me though I’m sure there’s an obvious reason.
Was just one of those things that made me go, ‘hmm’ today

 

Ppp

I’d get the Toyota TRD pads if I did it all over again. They come with the nice shim/silencer that are rubber backed. I bought the shim/silencers for some other pads (already previously acquired) and should have just bought the whole package with TRD Pads included in retrospect.

Currently on PowerStop Tow/Haul Ceramics with Toyota Shims. Pretty good.

 

Leds generate heat in the circuitry not at the light source. They can generate a fair amount of heat and if they get hot
Enough they’ll get dim

 

They are FN countersteer type x is the name i think. Have the tires in my garage, and ganna mount them this week. Have to test fit at home as Im not 100% the tires will fit.

 

Got the old trans pan removed. I now know what ATF tastes like. Not bad, almost medicinal. I didn't find any metal shavings on the magnets! The only thing on there is that gray sludge you find on the differential magnet.

I got the filter swapped out but I ran out of daylight before I could install the new pan. I'll tackle that tomorrow. In total I had over 8 quarts of fluid come out.

 

Looks like cherry flavored cough medicine.

 

It looks like this last weekend was the time for the first gens to go towing!

I hauled a bunch of stuff about 200 miles away to prep for moving at the end of the year. The truck did great! Would you believe this yellow thing weighs over 2500 lbs empty? I think I hauled about 4000lbs of stuff on the way down.

On the way back, I met up with a couple friends and went camping for three nights. I didn't want to drive back for the trailer, so I took it off-roading with me

After all was said and done, I traveled about 500 miles, averaged 12.5 mpg on the drive down (highway), and 13 on the way back (off-roading & camping).

According to my obd2 reader (courtesy of PHM), the trans didn't get over 160° on the way down and 165 on the way back.

Overall, I am impressed and proud of the ol girl and the trip was pretty fun!

 

Nice little present for yourself.

Happy birthday!

 

They are Mark Sumitomo Pads. Not TRD as I had wrongly mentioned yesterday. There are two styles of Sumitomo.

 

Gears don’t make more power, they just change out the drivetrain gets the available power down, when you change tire size you effectively change the final drive ratio. If you go to High if a gear, it will accelerate faster, but you’ll be doing 3,500 rpm at 60mph and lower your top speed

 

Based on your conditions, I’d keep the original gearing. Better gas mileage with the original gears at highway speeds. I’m on 285/75/r16 (32.8).

I do a mix of city and highway with tow/haul on original gears.

I’d *possibly* do new 4.56 gears if the truck was just rear wheel drive or possibly not. If most driving is highway I don’t think its worth it for me as both axles would need re-gearing with 4wd.

 

4.30 interests me just because I already have a perfectly fine front diff with 4.30s... rare bird, but they exist

 

I’d be just as interested as you with access to choice low price used Toyota donor parts and a lift and all the proper tools to do the job in half the time.

 

My truck has the limited slip differential, but 260,000 miles on it. Do I need gear oil with the LSD additive or is it safe to say the clutches have completely worn out by now and and it's not really a limited slip anymore?

 

Here this will keep you busy for a week or two....

Use Lucas 80w-90 with LS already in it. Its dino oil. Good to use recycled animals and leaves for the environment.

More power to you if you have the $$$ and skills.

Most of my philosophy is based on keeping the truck OEM optimized utilizing timely/orderly preventative maintenance techniques. I’ll spend money on her for an upgrade that is proven and cost effective. Most of my non-OEM stuff is very low cost/free tinkering.

 

You don't need to know all that info to figure out gearing for daily driving...
