Thanks for your reply, but I think more is needed. In this case it is more the second senario. I can idle and rev the engine with no knocking. The knocking only occurs when driving and becomes more rapid at higher speeds. Sounds like a bump, bump, bump, ... continuously while driving. When I stop, no knocking. The car shifts very smooth through all gears and reverse.
Not yet. With this being an older vehicle I wanted to try and gain some insight first. Not sure if it is worth repairing...
Thanks Pete. Going to seek out an inspection. With either of these senarios would it be safe to drive to the shop or should the vehicle be towed?
Pete, I took your a advice and made an appt to have a mechanic do a free diagnosis of the problem. Thanks.
