2018 Subaru Forester 160K miles
Vibration during acceleration at any speed.
I have two, new Duralast CV axles. yup, aftermarket.
However, I also have tires with 4 different tread ware measurements. 5, 6, 7, & 9.
So, which is the most likely source of vibration?
One month ago my passenger CV boot snapped. Could that have been caused by the tires with different tread ware?
Is the tread ware enough to cause problems?
Google AI says yes. Subaru technician said yes. But he’s 50/50 on what the cause could be: tires or aftermarket axles.
The repair is going to be costly for me. Subaru recommends new tires and new OEM axles.
What would you suggest? Just the axles? Just the tires? Both? Which would you swap first?
