Awhile back I was experiencing a thumping and vibration in the front end. It was found to be a sticking caliper. Got both calipers replaced about 6-months ago and all has been well until recently. Again I'm experiencing a vibration but it seems to a little different. It comes and goes now and starts around 55-60 mph and lasts for about a minute and then goes away. I am not hearing any roaring noise like a bearing. The vibration is very noticeable but like I said it eventually goes away. Anyone experience this before?

 

Hey buddy it's probably most likely your front and side engine mounts are done that why you get that vibration when going 50-60 mph. Take it to a shop and ask them to check it out your engine mount I'm sure that what it is .

 

I had these replaced under extended warranty awhile back. How many mounts are there?

 

There is four of them one in the front of the engine, one on each side and one behind the engine.

 

OK thanks I will call Acura and ask how many they replaced. I am confused why this would cause vibration at said speeds and then it smooths out.

 

There are three, not four. A front, rear, and passenger side. The transmission is on the driver's side, where there is no engine mount.

 

I'm still confused why this wold cause a temporary vibration? Two of the mounts were replaced and I think the rear one wasn't if there are three.

 

hmmm.....I would rotate my tires and see if the problem follows or goes away.

 

I had my mechanic look at the car today. He drove and checked all suspension components and inspected tires and wheels. He said when he spun up the tires on his machine two tires had a little hop to them but nothing major. Wheels are not bent so I am taking it back to the tire store and having them re-balance and and check the tires and rotate.
