nothing will fit Toyota gears other then Toyota gears. Unless you replace the entire rear end. Then you have to deal with other major fitment issues.

by "entire rear end", he meant the whole axle assembly, not just the differential. the only diffs that fit the 8" toyota axle will be a toyota 8" or 8.5" diff (with some modification of axle housing). don't even waste your time looking at other vehicles rear axles for such a simple fix.

you should be able to easily find a complete 8" toyota 3rd member in the 4.30 ratio for pretty cheap (like $20-150), since it was a stock gear ratio. you can also swap in any Toyota 8" diff with a different stock gear ratio, like 4.10, 4.56, or 4.88 so long as you also swap in the matching IFS differential if you want to use your 4wd - usually pretty cheap for IFS diff after someone SAS their rig and considers it "trash".

since you said your other diff laying around is a 4cyl diff from a 5spd, it is most likely 4.10 gear ratio (but you'd have to count the teeth to be 100% sure). you CAN use this diff to get your rig drivable, but since the front still has 4.30 gears you won't be able to use 4wd and many would recommend removing the front driveshaft to avoid any possible mishaps if anyone else drives your rig and/or "forgets". i would think a 4.10 IFS diff is the most abundant front diff laying around in a junk pile after people SAS - this is because many "mild wheelers" seek out the factory 4.56 and 4.88 diffs for their larger than stock tires (31-33").

as an option, many tacomas/4runners came with 4.30/TRD e-locked differentials as well; so if you are wanting an e-locker and have some fab skills to modify the axle housing, you can have a fancy selectable locker without having to change the gears on it (which will save a good amount of money). sure, it's not cheap - but it's a selectable locker

Just swap the differential instead of the whole axle. Then while you're saving up to do the gears, you can rebuild the other to basically brand new and have a nice shiny assembly to install. Unless you know everything about that axle you have sitting around you risk something failing on that one if you swap it in: seals, bearings, brakes, etc. Not saying it will happen, but possible. Just make sure to not use 4wd in the meantime.

If you do a lot of hwy driving you might actually pick up 1mpg with that gearing. I had my highest MPGs with 4.10/31" combo but I did mostly hwy. I'd think twice on that body lift unless you need it to clear an engine swap or flat belly without cutting floor pan. I have 33x12.5 on about 1-2" susp lift and some slight cutting - no rubbing and lower COG.

Noob question about gearing. I have 4:10 in my t100 right now. Do 4:88 really make that big of a difference?

What size tires are on your t100. There is a big fife range between 4:10 - 4:88. I know for the stock 22re pickup 4:10 are for a 29-30 inch tire and then 4:30 for a 31", the. 4:56-4:88 for 33", then 5:29 for 35". So yea it will make a big difference but you should match your gears to your tires so you don't tank you fuel mileage. Just my ignorant opinion but thought I'd share it anyways.

Hahaha yes that was me when I had a Prelude. Something was always wrong with it so I was always on the forum.

I'm new to this site, owned a toyota pickup 6 months now and debating 33s or 35s cause my 33s are loud and old. Looking into regearing my 1994 pickup or what else I will need besides 4.88 geared differentials to run them with my truck. (Assuming I need both front and rear?)..


Thanks for the noob links I saved the page
