Well for the past 2-3 weeks my G has suddenly started Quivering is what I call it when I hit the brakes. Well I live on a dirt road so I thought hmm, maybe dirt or mud or something. Or maybe Ive hit water (since I drive 40 miles to work every day) while they were hot and warped the rotors. Well this morning I took the G to the brake shop, he drove it, checked the front end, the brake pads (only 6 months old), and the rotors. He said it drove perfect with him, everything looks fine, didn't even charge me anything. He did however say well the front end does feel a little "off", but I think it is more of a drive train problem or an ABS problem. Well he took it across the street to the Mechanic's shop to let them have a look. I have put new brakes, rack and pinion, front end aligned, and two new rear wheel bearings within the past year. (Had to replace the left rear wheel bearing twice due to the first one wearing again which was covered under warranty). Could the front hub assemblys be going bad maybe, or a ball joint or something? The car drives smooth as ever, literally floats. The tires are fairly new also. I just feel like something is off. And for some reason shifting between 30mph and 40mph is awful rough I've noticed. Owned my G for 5 years. Maybe I'm just wigging myself out. Any input?

 

Tire Balance? Air Pressure?

 

The tire/brake guy said tires were perfect, air pressure, brake pads, everything perfect. It is still at the mechanic's, haven't heard word yet. I will keep you updated. Thanks for the input!

 

What condition are the suspension bushings in? Compression rod bushings?

 

I'm hoping in good shape. According to the "mechanic" he said according to him driving it, a machine test, and a "look about" he couldn't find a thing. Brakes weren't shaky this morning. But once it heats up this afternoon here in Georgia (90 degrees plus), they will begin to shake. Weirdest thing. I think living on a dirt road has taken it's toll maybe. Time to upgrade to an infiniti higher off the ground maybe.
