4g BB4 front hub/knuckle compatibility?

No bud. Fronts. The sensor fits into a big hole that reads the abs ring on drive shaft. Non abs hubs dont.

It bolts on the upright and points down on the ABS ring. I'm pretty sure Non-ABS ludes have the mounting holes for the sensors as well, but I could be wrong on that.

EDIT:

This is my 5th gen's...

Only just realised this is for the CV joint ring as aposed to the hub The hub ABS ring applies to the rear.

I'll have to look at my 4th gens (Which are both Non-ABS from the factory) to confirm whether they have the mounting holes as well.

Yea on the outer part of the hub as that's 5th gen. From memory the 4th gen abs sensor goes through a hole in the hub. This hole isn't there on non abs. Unless I'm remembering wrong.

newkid is right - 4g non abs front hubs are not interchangeable with cars fitted with abs there is no cut out for the sensor and there are no holes for mounting the sensor in place. You can however fit abs front hubs to a car that doesnt have abs or at least i couldnt see any fitment issue when comparing them side by side.

Have you got a pic of this hole? I don't think I've ever seen it.

No rude pics please

ive can email you pics of the non abs one i have here that came off a BB4 - the abs ones are now on my BB1-had to use them as i couldnt get the driveshafts out of the knuckles-they were seized solid.
