I cant' see anything going to back of the front wheels, except brake line.
I just added a new abs in the differential so I know it has that.
I need new bearings up front (loud rumbling) So I went to get two front rotors. The O'Reillys guy wants to know if I need the 2 or 4 wheel abs rotors..???
So I'm thinking it must be 2 wheel abs, sense the only thing I can find or know about is the sensor in the differential

So for the 97 b2500 models it reads the rear wheels only and that by sensing the differential gears....
So I got 2 wheel abs???? Thanks for your time and advise...

 

the vehicle information sheet I got from the dealer says--Pwr Disc/Drum Rr Anti-Lock Brakes...
Does that mean there's only rear wheel abs...????

 

Yes it does.

 

Thanks alloro-- now I know which rotors to buy...(2 wheel abs)..
Now all I need to do is measure the rotor, to see if it's with'in spec's..Which means I need a caliper...Thick I'll borrow my neighbors..

 

only reason I would replace rotor is if it is grooved or warped and your brakes pulsate when braking...

 

Yea, rsdata- ,,I could have saved a hundred bucks, yet I just thought it must have the same rotors from 97, and I don't have a way to measure the thickness for minimum thickness. So I'll have to take it to a brake shop, and beg someone to do it for me..
Do you know I bought new tie'rod'ends inner and outer, new ball joints with all the bushings. for all the front end suspension..And now that I found out the bearings are what's making it so loud, and loose, I might not need them..
I"ll hang on to them though..because I want to keep this 97 b2500 ram van. Even though it might take me a very long time to make it into a comfortable insulated living on the road van..Someday...now I need to get those large socket's for the bigger bolts and nut's...One day at a time...
