I've had my 1991 for a week. More catching up on neglected service/maintenance items:
Brake bleed/flush - nasty stuff came out of passenger rear. Never seen a brake line so bad...
Front Diff oil - there was not much in there...
Moly in the birfs (from the top, sandwich bag style) - not much in there, either. Went thru 2 tubes of grease (the bag method is pretty wasteful, mind you). Will add more.
I've got a soup issue on the driver's side, so I'm likely tearing that apart. But discovered a very blocked diff breather when adding/checking the oil. Pressure had nowhere to go but out the seal. Cleaned the top hat and re-installed. So maybe the axle seal will leak less now. Will be keeping an eye on that.
Complete PO's part-donkey de-smog. He was running the short belt to bypass the air pump, but had left the EGR intact. I simply bb blocked the two vac lines on top of the throttle body - based on vac diagram and reading here, they are what runs the EGR. Truck is definitely less stumbly under acceleration up to 2000 rpm. Sounds better, feels better. I suspect the egr was badly clogged and not functioning properly. I haven't actually removed any of the smog system stuff, so I guess my approach is halfassed too.
Disconnected EGR temp sensor and connected the ECU side pins together. Hopefully that makes for goodbye CEL code 71. So far, so good.
Rear hatch crazyglue trick (replacement struts ordered).
1 million point lube (hinges, locks, u joints, prop shafts, cables, linkages etc)
Rubber protector on all rubber seals.
Rust guard inside door bottoms.
Phew. Productive weekend. And now back to the office with grease under my fingernails.
