Re: front diff

There is no drain plug, the fluid has to be sucked out of the filler plug. I don't remember where the filler plug is, but it's a PIA.

Hit? Them tires rub. Rubbin's off roadin.

Re: front diff

Yes very easy. There is only a fill plug so you need to go to the auto store and buy a syphine of a manual hand pump to suck the old out. It should be near the gear lube shelf. Then when it's all out fill up until gear lube starts coming out of the hole. Then put the fill plug back in.

<font face="Comic Sans MS">Go to the store and buy yourself:<ul>[*] One hand vacuum pump with guage (these things come in handy more than you'd expect)[*] One brake bleeder cup to go with said vacuum pump. [/list]This combination works great. Hook the vacuum pump up to the fitting on the bleeder cup (usually on the cap that screws on) that does not extend into the bleeder cup. Hook a line to the other fitting and put that into the fill plug hole (on mine the fill plug hole is on the passenger side near the front of the differential (on the diffy obviously)). Then just pump the vacuum pump and watch as the bleeder cup fills up. Empty the bleeder thing when it gets near the vacuum port that the vacuum pump is connected to (we don't want gear lube in our new vacuum pump). This seems to be the best way I've found to do it.
