Originally posted by TonyNYeah, a pickup front or rear diff will fit. Check your gearing is the same though or 4wd will be no good
Thanks Tony, any idea what ratio's i've got to choose from? I belive colour codes are used on pickup's (blue or yellow) are surf's the same?

ah, you have a 3rd gen. According to charts A05B is a 7 1/2" (?? should be 8", but this has been wrong on other trucks), 3.15 gears and 4 pinion.
The 4 pinion could hard to find, most pickups are 2 pinion which isn't as strong.
You may need to find a used 93-on Surf diff to get a 4 pinion diff.
3.15 is very high, not seen gears as tall as that in a 2nd gen Surf of pickup.4x4toys.co.uk - Keeping you on and off the road...

Thanx again Tony, I did not make myself very clear, my fault. I'm looking for a diff for my UK double cab pickup. That code is from the pickup. The diffs on my surf are fine. I'm looking for a surf diff (maybe) to stick in my pickup.

OK, just been out in the sub zero tempretures under my truk checking ratio's. The diff is definatly a 4.3:1 (so is the front, so thats good). What i need now is imformation on the size. How can i tell if it's 7" or 8". Please dont tell me i need to drop it out (not in this weather)

Looks like i'm looking for a 4.3:1 8" diff. Are there any issues with the amount of splines on the shafts?
The yanks got an uprated diff for late model bigger trucks, the easiest way to spot it is the diff bolts, the old 8" diff has 12mm bolts holding it in, the bigger diffs have 14mm bolts.4x4toys.co.uk - Keeping you on and off the road...

Originally posted by oilyTony, are you talking about the ring of studs that hold the diff into the axel case? if so, are you talking about spanner size (12mm/14mm)? cus my studs are only about 8mm but the nuts are about 12mm. is this right?4x4toys.co.uk - Keeping you on and off the road...

Yeah, that's what i'm thinking. OK has anyone got a GOOD (No whining/knocks/bangs/rattles etc.) 4.3:1 8" diff they would like to find a new home for with the right amount of beer tokens changing hands?. Bear in mind that if it's 3 billion miles away from North Worcestershire, it needs to be postable.
Thanks for your help Tony. Top Guy

Just for information, I've now pulled the diff and despite the vin code etc. it's a limited slip and it is 4.3:1 ratio so the lesson is dont trust the codes on later toyots. very confusing.
Thanks for all your help and i think i'm half way to getting it sorted.
