2 wheel abs, 4 wheel abs, identifying

[BadGT04]

Im about to be purchasing a new wheel hub and noticed when ordering parts you can get the hub made for 2 wheel abs or 4 wheel abs. How do you tell if your truck is 2 or 4 wheel abs before starting disassembly?

really? well if the truck is 4wd then its 4wd ABS.
2wd, 2wd abs..
do u know the truck as ABS?

The easiest way to tell would be to look at the front spindle and see if there is an electrical wire going to the spindle. The 4wheel ABS trucks will have a wire that goes to a sensor which reads pulses from a toner ring on the hub assembly.

The 2wheel ABS trucks don't have that sensor or the toner ring on the hub.

PS if the truck is 2wheel ABS, its ABS on the rear only... just FYI.

Not true... My truck doesn't have 4 wheel ABS, yet it has the ABS sensor in the front hubs, complete with wiring. I know the truck doesn't have ABS because my insurance went up due to it (ABS is a discount), and, well, if you lay on the brakes, the tires lock up.

Just buy the 4wd hubs. They are cheaper. Just run the cable up to the frame and zip tie it up.

Edit: Or you can even connect the wiring. Even the 2wd trucks have the wiring, but not the 4wd ABS module.

Agree, if in doubt buy the hubs for the 4 wheel abs truck. I dunno, my truck has 4 wheel abs, so I just figured that was why it had the sensors, haha. But I guess it would have them even if it was only two wheel abs.

All the chassis have pretty much the same wiring to save money.

[BadGT04]

So if I bought abs wheel hubs for the front and plugged em in, I would automatically have a 4wheel abs truck?

[Dirk]

No, you just have the wiring for it.

Thanks Dirk!

That's what I was wondering!!!
