well im pretty sure my truck is making the death chirp..started two days ago and is bad enough that im worried about driving my truck. was quoted by an repair shop that if thats the problem, itll cost around 200. im not real mechanically inclined, so im debating if spending the extra cash is worth having it done professionally, or if i should attempt to fix it myself. what do you guys think?
