Well I ought to chime in now, The LF wheel bearing on the Bonneville
began growling enroute to Lousiville when we were two hours away from
the hotel.. The noise would start at 23 mph. Kind of figgured it was the
WB making noise, it got louder the faster you went. I drove around 450
miles at 65 mph without problems.
The 89 Z - 24 I bought used in 1996 had a bad wheel bearing when it was
traded in. The WB only made noise over 70 mph. No noise during the test
drive which got up to only 60 mph.
Regular city driving you'd never know it was bad unless it would
eventually make noise at a lower speed, which it didn't .
Second front wheel bearing to go out on the Bonneville made noise at
about 30 mph, but did not get louder when you went faster.
