So I got my truck from my dad a little more than a year ago. He had it for 5 years or so since it had 70K on it. Now has 140K. He is a stickler for normal maint and records everything. Less than 15K miles ago he did all new brake pads, rotors, and bearings on the fronts (and he is not a novice at this). I started noticing some shaking coming down a few hills. It just got worse and worse. My dad told me it couldnt be brakes cause he just did them all, had to be my driving. He finally looked at it for me and found a snapped bolt in the suspension and the pads on one side were about toast. We replaced those but it was still shaking coming down hills and kind of pulsing and i could feel pulsing against my foot from the pedal as I would steadily brake coming to a stop sign or light. After several others opinions I got new rotors and installed them with a buddy and his dad (his dad had a respectable mechanical background). He pointed out to me that the passenger side spindle is going to need to be replaced. We re-packed the bearings and put it all back together and there was no shake, it finally was running and braking perfect. Then after a few days and coming down some substatial hills, today the red brake light and ABS lights both came on and have stayed on. Any ideas? Brake fluid and lines are good. Could it be that spindle? Here is a picture of the worn spindle
oh and the ranger is 2wd 4cyl 5spd. 2wheel ABS
