Just diagnosed failed Vacuum Pump on my 04. 5 3500 6 speed SRW LB Jacobs E-Brake. Sounds like a card in a bike wheel, no vac to brake, w/power to switch. Have found new Mopar part 5102084AA at Newmoparparts.com for $570. Any other solutions or sources I can check? Seems pricey for the pump. I plan to replace the original belt until I come up with a good/less costly solution.
