Sudden Wobble - 560 SEL

[halman2228]

Out of the blue, the 560 developed a fairly severe front end wobble, as if the wheel is about to fall off. Very bad at low speed, moderates somewhat as speed increases. It also has a moderately strong pull to the left (sudden onset) as well. The wife does not recall even a minor pothole encounter...

I've done a preliminary check for something obvious (dangling idler arm, lost ball joint) but haven't put it up on the lift yet.

Searching herein, the first supect is a tire gone bad so I'm going out to switch/rotate the tires. I'll check back in with results in a little bit.

In the meantime -is there any other item that could fail that suddenly without some prior indication of impending failure?

Best regards to all,
Kevin
