I have had some problems with Bell recon VCUs, but they have been very good at sorting them out.
One support bearing rubber perished and failed after 1 year.
Another support bearing failed after 18 months.
A recon VCU failed after 20,000 miles, completely seized. It was a needle roller bearing, which perhaps should have been replaced at the recon. Quite a rare occurrence, apparently.
With that in mind, I would still recommend Bell, but get a VCU without support bearings and fit proper GKN ones. The bearings should be branded ‘Fag’.
