>>> I had lots of left-front bearing noise of late, worsening over this last 1,000 miles or so — despite having new bearings put in 36,000 miles ago… though by a mechanic back home in Denver who proved more than a little shady later. BUT, we are full-timers and overloaded on weight a bit, so premature failure was somewhat expected anyway.
>>>
>>> Regardless, early this week I had an independent VW mechanic install new inner and outer bearings on both fronts. When seeing his shop, faith took a dive but I gave the benefit of the doubt. When both bearings came loose in a one-mile test drive, faith lessened. < Yes, he reused the retainer nuts which I later learned is as spooky as it gets! >
>>>
>>> When the speedo suddenly didn't work, and brake pedal pressure was equally-suddenly inconsistent, he passed it all off as "coincidental" and my faith went to zero. I do not think he opened any bleeds or anything else to introduce air. He did not put anything between the front pads to keep them the proper distance apart. I believe I had new brake lines installed 36,000 miles ago. I had him bleed the fronts a little and re-adjust the retainer nuts (getting spookier!), and though the brakes were the same, at least the wheels didn't fly off on the drive to Miami!
>>>
>>> But as eluded to, the worst part is my perfectly-functioning brakes are all over the place in pressure: One heavy braking, all the way to the floor... Pump them once or twice, fine... Next time, same or somewhere in-between. Said mechanic claimed it all as total coincidence, or that the rear brakes needed adjustment. Huh…
>>>
>>> EVERYTHING but the bearings were working perfectly until he opened his toolbox.

>>> I limped it 80 miles to a friend's in Miami. We just bled the brakes as per the manual, RR first, LR second, RF third, LF last. Lots of air in there from a quite-baffling source. After bleeding the pedal was nice and stiff as a board. When I fired it up, the pedal goes a little softer but I think this is normal. First time on out road test the brakes went to the floor again.
