It's a bad tire. If you zoom in you can see how the surface of the tire "dips down". It's like the tire has a hole in it. It's one of the newer tires also. This is my first time seeing a bad tire. I guess the moral of the story is..."if it sounds like a bad tire...check the tires". Thank...

Odd. I put the spare on today. Replaced the wheel that hit the curb a couple times. The thumping is still there. I guess I could change out the other three tires. That would eliminate a tire problem. The sound is hard to isolate.

Thank you good tip, I will check this next. Is it possible that hitting a curb can damage the tire?

Hmm. Thank you, made sense to me to. But that did not work...and was a hard repair due to the lower control arm being a pain. So, still the same problem. Thumping from 14-22 mph. Can rule out passenger side wheel bearing or CV axle. I checked the other wheel bearings. One was making a...

I got a 2013 Dart auto with 125k. I'm getting a thumping noise between 14 mph and 22 mph (sounds like the front passenger wheel). I thought for sure it was the wheel bearing so I replaced it...wrong. I will admit to hitting a curb or two really hard (yes I'm stupid). I checked the three...

It's a turbo yes. I am still agreeing with the piston hitting the two exhaust valves, even though I can't see a mark. The turbo is fine, the car was running well before I removed the cylinder head (just running on 3 cylinders). Will there always be a mark on the piston if it hits a valve?

I cleaned the top of the piston with a little brake cleaner. I can't see any marks on it.

Looks like you guys knocked it out quick. I put a valve from #2 in and it sealed perfect, barely had my thumb on it. I have to order at least two valves, does the cylinder head and piston normally survive something like this? The valves in #4 seem to be going in tight like the other...

The previous owner told me he had the timing belt replaced, so I checked it out and the timing was spot on. However, he did say the belt was "making noise" before that though, so who knows what happened. The other valves were tight, so I should be able to use one and see if it seals in #4. I...

I have a Dodge Dart 2013 1.4 liter turbo with some valve trouble. Initially (this car is a mechanic's special), cylinder #4 lost compression...so I pulled the head. The head seems ok but the #4 exhaust valves are "popped" out of their seats...maybe 1/16"...just enough to lose all compression...
