I tried rebuilding mine.. 7K axles....No Bueno.. Better off buying half shaft if you have ability to.. Otherwise I would consider using a boot stretcher to slide boot over the end.. I couldn't disassemble my half shaft without distorting the CV cup.. I honestly don't think they were made to be rebuilt, looks like there is some welded parts that were done during assembly and thus make them unserviceable,,,, Unless you have a boot stretcher, not sure its possible to rebuild.. Just my experience.. Someone else may chime in here..
PS: will need Oetiker clamps and tightener to fasten boot
PPS: Amazon I believe has services in Spain now.. Might be able to source half shaft that way.. And a lot of other HMMWV parts..
PPPS: On Amazon I found :
GSP NCV82075 CV Axle Shaft Assembly - Right Front (Passenger Side)
About $150 shipped to Spain via Amazon.. You'll need to do a little research to make sure you're getting the correct Half shafts but I believe you'll be able to find what you need at a reasonable price.. And All the HMMWVs were upgraded to 10K shafts when the were serviced/replaced.. I replace mine as they fail.. I have (2) 10K and (2) original 7k on my 89' 998 currently.. Not an issue..
Ocho Out !!
