Q: Starter is loose

Hello a loose starter is something you should have repaired and inspected sooner than later to avoid damage to where the starter mounts. If the starter brakes it mounting tabs or cracks the mount, the repair could be expensive due to the replacement of the transmission bell housing, engine block, or stripped threads. You should have a mechanic do an inspection of your starter. If you catch it soon enough, you can have this issue addressed before any further problems occur.
