Dad's truck: '04 Dodge CTD Quadcab shortbed. Are there speed sleeves available for the rear drive shaft? The xfer case was toasted a while back and the replacement xfer case ran low of oil from a leak. I replaced the rear output seal on the xfer case and cleaned the shaft. The shaft was noticeably burnt but not scared up. I'm continuing to monitor for leaks but.... I don't want to replace the seal again. I also posted up in Cumminsforum but it appears no replies as of yet.
