Thumping Noise Over Bumps on the Right Side and a CEL
What the customer reported
The vehicle owner reported the check engine light (CEL) was on and a thumping noise on the right side when driving over uneven pavement at slow speeds.
What we found and did
The technician tested the vehicle to look into both concerns, and the notes said it may require further testing. Testing found that the purge valve/solenoid failed testing and needs replacement, both front sway bar links are very worn, and the front lower control arm / ball joint has excessive play. Only the testing and a full synthetic oil change to vehicle specs were performed on this visit at our Lake Wales shop, and the other items were listed as recommended work.
