Hello all! First post here, thank you for having me. I am a noob mechanic, and was working on replacing my front shocks on my '04 Xterra. The top nut was rusted and stripped from the previous owner trying to do it himself I am guessing. I ended up cutting it out, and cut my ABS line in the process. I left it alone as finances are tight, and I don't want to drop $40 on a new one just yet. I had a shop replace the upper and lower control arms, as I don't have the skills to do so myself, and in the process, they went ahead and replaced my calipers on both sides as well since I had the parts in my trunk. (the head mech there likes me and did it for free) After picking it up from the shop, I noticed at 20mph I started hearing a noise akin to a baseball card in the spokes of a bicycle tire. I slowed down and it stopped when I dropped to around 15-20mph again. I assumed it was the slide bracket for the brake pads rubbing against the rotor, and decided to reach the speed limit of 35 mph and just get it home. I did so, heard the noise increase in volume slightly, then heard and felt a THUNK, and all noise went away. It has done this 85% of the time I drive since I picked it up from the shop a few days ago. In looking online, I am actually thinking it is the ABS self test cycling because I cut that line and have one good side, one bad. Do you think this is accurate? If so, would pulling the ABS fuse be a short term fix? Or would replacing the line be the best? Am I damaging my truck by driving it like this? If this isn't the case, what do you think it could be? Thank you for reading the whole thing. Haha. Any insight would be appreciated.
