hey i have an 82 toyota 22r and i just put some 33x12.5 on it, now i have only owned the truck for a month or so.
(however a good friend of mine owned it previous to that and it was a daily driver, so i know the history behind it)
but when i put it in 4x4 high it doesnt have enough power to move it, if your on flat ground you can get it moving ok but its a little sluggish and if your on a hill then you cannot start out on the hill without stalling out. and i mean even on little inclines in a mud pit

works fine in 4x4 low, and i know thats mainly becuase gearing but i was wondering if there was anything i can do to help out with this problem????

 

How is it otherwise? Sluggish with little power? With tires that size and stock gearing it'll be sluggish. Add a need of a tune up...plugs, wires, cap & rotor, maybe timing, valve adjustment, new air cleaner etc. and that could be all it is.

I don't know all the different gearings like some people do, but 4HI has always been a bit sluggish for me. I don't think it's geared all that low, but you're suddenly pushing four tires instead of two, so it'll feel sluggish. But yours sounds pretty bad so I'd look into your engine's performance in general.

 

5.29s

 

4 low .

 

I notice no performance difference in 2wd or 4wd hi with my truck on 31 m/t's.

 

so crolison, you suggest maby i need a lower gears in the rear differential of just the front??

 

BOTH!!!

If you learn best from experience, feel free to re-gear one axle and not the other. Put 'er in 4wd and you'll get a good lesson.

Front & rear axles must be geared the same.

With tires that big you ought to re-gear. But I'd still check into engine performance issues.

 

well ive already tried the "performance issues" plugs, caps, air filter, carb, pretty much everything

but are you sure that you have to regear both axles, i mean that would make sense.
But i thought that the front axles were already a different ratio

 

you have a 4x4 which means you need matching gears in the F &R.

If your front is different from the rear some one was a bonehead. they need to match.

 

Both axles SHOULD be the same if un-touched by other owners. If they are different you should feel some binding in 4wd. 4 low would be less effect on the motor but still churn the dirt. You could lift the tires and turn the driveline and count the rotations vs. the tire. Or pull the diffs and count the gears on the ring and pinions. I like 5.29's front and rear with 35's. 33's could use at least 4.88's.

 

yes i was just looking at buying the 4.88 set for my toyota, but i was wondering around what am i looking at paying for the 4.88 set??

 

Not really true at all..
I have 4.10s in the front of my pickup, and 4.30's in the rear.
I don't feel any binding offroad at all.
It just turns funny
Now, onroad, is a whole different story

 

hey i was wondering if you guys could help me out, because i called the drive line shop in my town and the guy said he would like to know the original gear size because he said that the new gears might be bigger in hieght and it might take some modifying

well i was wondering first of if this is true??? (i will be putting 4.88 in) and what the stock gearing is??

 

also i was wondering about the headman chikara 39400 header, its like 200 on summit racing and im debating buying it, but i was wondering since its a short header if it will still give me some HP gain??

and i was wondering if anyone has some headers that they would recomend because i want my moneys worth but i also dont want to spend a bunch, Any Ideas??

 

4:10 's .. and NO modifications are necessary if you purchace a good gear set .

.

 

OK, your gears are pretty close. I guess you would not feel much on loose stuff. You did that on purpose right? I have heard of that. Does it clime better that way? Thats what I heard people say why they did that.

 

Your truck is sluggish due to gearing. I run 31" or 33" tires using 4:88 gear sets F/ R and have no problems. When you go to lower ratios you loose strength on the ring & pinions The higher the ratio the weaker the gears (4:88-20% loss). If you buy high quality gear sets you should be okay. Be absolutely sure the ring & pinion gear set you purchase does not use a spacer; they are junk. If your going to the expense of putting new gear sets in you should put positraction units in as well. I have run Gleason gear drive type positraction units for 26 years and 150,000 miles of racing and street driving with no problems. I use Mobil 1 gear lube in my rears, transmission and transfer case. My Toyota dealer pulls them for inspection every five years and everything looks almost new.

 

I'll add something here...I haven't driven my first gen very much yet, still fixing issues as they come up. However, when I first bought it the gearing was still stock, 4.10's, and it had 35x12.5's on it. It could move just as good in 4hi as it could in 2hi. I think there may be something else going on here, like mismatched gears or something. A buddy of mine bought a rig without knowing it's history and it wouldn't even crawl at idle in 4lo, turns out somebody had geared it to 5.29's, but we suspect somebody blew up the rear diff and just put a 4.10 open diff in to get it driveable. So unless he was on pretty loose dirt, the 5.29 front/4.10 rear setup would bind enough to kill the motor. I think you should research a little bit and try the tire rotation method somebody suggested above and see if your current gears match.

 

No, i blew up my 4.10's. My entire axle case was filled with mud and water and i forgot to change my "oil" in the case.. So it blew my pinion bearings and chewed up the carrier bearings on the 3rd.
It pulls faster in the front than in the rear, so the rear tends to drag a bit.

 

If his gears were that mismatched, 4lo would be bad too, not just 4hi.
