Here's pix of my LCA bushings (big rear bushing) at ~ 60,000 miles. New LCA's were installed shortly after these pictures taken. In the 2nd pic, left side control arm, one of the 'spokes' is torn completely through horizontally @ 7 0'clock position. When jacked up with the wheels hanging down, the upper and lower halves of that 'spoke ' shift opposite directions sideways indicating a clean break and not a surface crack. Also tears at ~ 10 o'clock and small tear at ~ 2o'clock. Notice 'spoke' at ~ 5 o'clock position tearing away from metal center bushing.
In the first picture (right side control arm) it shows similar and notice along the circumference on the left half that the rubber is separating from the heavy casting.
I don't have rigorous driving conditions (some roads are lousy with patches and could stand resurfacing but they don't jostle the car around too much), just a lot of stop signs and lights from in- town and suburban driving. You can tell that the bushings have been degrading for some time, this didn't just happen all of a sudden at 60k miles.
These were not the original bushings but were "updated' bushings installed per TSB back in 2014 right after I bought the car because of my complaint of squeaking. They fixed the noise and they also improved the ride.
Pitter, it would have been interesting to see the condition of the bushings in your LCA's just for comparison.
