ABS light came on, replaced master cyl with brand new one (bench bled) bled brakes RR LR RF LF light still on. Cannot locate sensor ring to try cleaning.
#2 problem: After I use 4WD and go back to 2WD, the truck is binding somewhere and then goes away. Fluid in front was low and replaced to full with same. 1995 K1500 Chev base model 4.3 5 speed

 

How many miles?

 

114181.9

 

Is it the right side that is "grabbing?" I'd put a jack under it, and remove the wheel (right side) first, then feel what what play you might have. Sounding like a front axle bearing with that mileage.

 

Will try, but the constant is the wheel bearing is there with or w/o the 4wd in or out. No problems in 2wd. Any thoughts on a miss under acceleration that feels like water in the gas. New OE pump and HD strainer, filter too. Did code EGR fault and replaced valve and position sensor tested OK. No codes retained now. I know, it's a $500.00 truck but it's still a truck that this old parts man cannot figure out. Still runs @ high RPM w/o the miss, so it's getting fuel there.

 

That is what I was going on. My 2000 Suburban at about your mileage had the bearing problem you described.

 

OK, I'm on it, thank you for your input.
