2007 Chevrolet Impala 1LT
3.5L Flex Fuel Engine
All maintenance kept up per recommended schedule
PROBLEM: Possible broken left front strut and/or other damage?
SYMPTOMS: Hit a section of buckled road with a significant pot hole on far side of the uplifted segment of pavement on the highway at about 70-75 mph. (Surprised I didn’t blow one or more tires!) Car now has a loose rumble in the left front that is noticable on rough pavement about 70% of the time. I can hear and slightly feel the loose rumble in the front left wheel area. Steering and handling has not been affected. The overall suspension seems no worse than before (although this Impala has never had a very smooth ride.)
Mechanic inspected the underside of vehicle and found points of contact left and right middle of undercarriage, more significantly on left side. Found nothing loose or apparently damaged and could not hear rumble during 3 mile test drive over rough roads.
In all fairness, it is storming this morning with heavy rain and thunder. I kept the scheduled appointment to get the oil changed and this problem looked at anyway. Even I, knowing the difference in sound and feel since hitting the bad pavement, can barely detect the sound this morning. When I push down hard on each of the four corners of the car, it doesn’t bounce/sway any differently or more than normal.
The mechanic can find no apparent safety problem at this time and both he and the service writer recommend I drive the car for now and bring it back on a dry, quiet weather day for a second try at them hearing/feeling the rumble rather than just throw parts/money at the problem without being sure what is wrong. That seems quite reasonable to me!
QUESTION: Given that the point of contact is quite noticable on the undercarriage in the middle of the car, worse on the left side where I’m hearing the rumble, is there anything I should be concerned about in addition to the struts, shocks, and tires as having possible damage that can continue to deteriorate?
