Any/all wisdom on the below (longish-questions at bottom! ) would be appreciated!!! 1. Drive the other day became buzzy (humming from undercarriage).
2. Upon close inspection, visible portions of the universal joints looked as though they were 'crumbling'!
3. Upon removal of the 2 part drive shaft, hanger/center support bearing was observed to be quite chewed up!Good News: Found New Center Support BearingsBad News: As far as I can tell by my initial research and observation, the u joints were originally 'staked-in' to place (lip of some sort 'peened' to hold in place). AKA UNreplaceable.
Found a couple of companies offering staked in replacement joints inexpensively, but upon consulting with several driveline shops, was advised against such as correct refitment is VERY difficult due need for machine shop quality groves to be cut into input area in ordr to maintain true center line.
By not doing so, I am told that there will most likely be a definite vibration, related noise, and premature failure of the replacement joints.
The only other option seems a professional rebuild or new junkyard shaft.
Reputable rebuilds are looking in the $400 range for parts alone.
Junkyard shaft has that whole mystery life expectancy issue . Has anyone had experience in this area of JUSTY? Any trick to making quality use of the staked-in replacement joint kits? Thanks alot team, #891989 Subaru JUSTY RS 4WD 126, 711 miles

Wow stacks, I was told similar regarding the fit of the staked in (circlip) replacement joints (#2 *). #1 pain in the neck to extract the 'caps'
*#2 as the spin speed is so high, imbalances from DIY grinds/filing/dremeling are much more sensitive, whereas precision machine shopping will cost you comparable to complete shaft rebuild!As far as noises... that was an initial indication- a 45-50 mph 'buzzing'/hum sound and 'clunking'/'boomp' sounds upon engaging/disengaging 4WD. The local 'specialist' driveshaft shops out here don't want to touch the replacement kits... I'll let you know which route I go (Do it yourself, junkyard commando- luckily 40 degrees this week, or rebuild $$$ ). Hopefully someone here has a success story with those replacement stake-in kits... Thx, #891989 Subaru JUSTY 4WD 126, 711 miles

UPDATE: Found a fantastic used shaft from the Left/West Coast. Looked almost too gorgeous to put on the car. Never had so much as a sprinkle of roadsalt. Solved all problems. While searching for that driveshaft, also picked up a set of the 'staked-in' replacement joints. When I get to rebuilding the bum shaft, will post details...

you should have checked the for sale section. I was selling mine for $10 plus shipping with only 27,000 miles on it.
