rear axle grease fill question

I tried to grease the rear axle somehow one of the nipples is hard to reach with standard grease gun filler head, is there any smaller size head of the grease gun that is available in the market that could reach it ?

Huh ?
There aren't any grease fittings on the rear axle, it uses gear oil.

But anyhow, there are other attachments for a grease gun in addition to the standard push-on one for Zerk fittings. There are several types of needle fittings. 4WD Toyotas come with one to use on the double-Cardan joint in the front driveshaft (at least they used to).

you are right, it is rear drive shaft that has one nipple buried little down hard to reach for standard grease gun hose, so I have to look for some attachment to reach this spot.

This is one type of fitting

fourwd1,

Thanks for your pictures seem to be both fitting will help, so your point is the fittings will fit the standard grease gun hose, where do I purchase these type of fittings, do you know ?
By the way my 4 runner is year 2001.

I believe these tools should take care of my problem.
