Unhappy Need diagnosis help

I'm a retiree, so I have time, but limited expertise.

There is a knocking sound (sort of a thump, thump, thump....) that sounds like it is coming from the driver's side front wheel. As best as I can tell, the sound occurs at all speeds. It is very faint for the first mile to two, then gets louder. It seems to disappear when the car is not going straight, i.e., I don't hear it when I'm making a right or left hand turn or even in a curve in the road.

I've taken off the wheel but I can't see anything in particular that is wrong - can you Cruisers help?

First check the wheel lugs for tight. Sounds like a wheel bearing. Although primarily the make a grinding sound.

Thanks for the response. The lug nuts were very tight, I had to use a 30" cheater pipe on my wrench to loosen them. I fear it may be ball joints. I've changed the tie rods and lower trailing arms on a BMW 3 series, but the Cruiser is front=wheel drive and I fear it may be more difficult. Your thoughts?

Search on here and you tube. A crap load of PT stuff on you tube.

From what you've done I don't really think youd have an issue with the ball joints on a PT.

Welcome aboard.
