I was just wondering 4Runners have extended diff breathers as standard, I can't really be bothered going out and laying underneath it at the moment so I'm hoping someone might be able to tell me

No they don't, the back Diff Breather is a peice of cake to extend, the front is a bit of a pain to get the hose not to kink but is easily dooable.

I took the rear breather out, went down to Hoseco (local hydrolic shop) and picked up two joiners with the same thread as the breather. (cost about $3 for the two of them). Then got some plastic hose from bunnings and whacked them in, took about an hour to do both of them. They are both extended to the top of the firewall in the engine bay.

How long were the breathers that you took out, where did they end?

will21, they were just screwed into the top of the Diff, they are only 2cm long, basically just the top of the diff is where the water will get in. That's pretty standard issue on most 4bies.

Are Hiluxes the same? Or were breathers put on them cause they are seen to be a bit more of an off road vehicle?

They're all the same,

I think 4 runners were the first ones out with IFS.

Same meat, different gravy

4Runners came out with an IFS around 86 (??), I think it was to fit the V6 which came out in the 4dr models, IFS didn't make it into the SR5 hilux until around 92-93

Diff breathers are all well and good - but what about gearbox and transfer-case breathers? Same problem.

I have a LC100 with an auto box - anyone know where the breather is for that???
