Yes. Ideally it would be the same style and weight as the old one.
Sure it is done all the time. Just unscrew it and fluid will start dripping out. then just replace with the new one. Good luck.
yes
If you are talking about the crankshaft rod bearings, you can just remove the oil pan, and replace each crank bearing one at a time without actually removing the pistons. But to replace the piston pin rod bearings the pistons will have to be removed. IMO, if any of these bearings are worn bad enough to need replacing, then the engine needs a complete overhaul.
It is just about the hardest most difficult part of an engine to replace. The engine has to come out. The head has to be taken off. The rod of the piston has to be disconnected from the crankshaft. the top of the cylinder has to have a ridge reamer operated on it to get the piston out.
Sometimes. Look for screws or bold under neither. Mine just unscrew.
Which piston? what's wrong. If it's a piston in the engine, you'll need a major rebuild. If it's a master cylinder or wheel cylinder piston, just replace the cylinder, it's not worth the trouble.
It is possible to replace the air conditioner clutch without replacing the entire compressor if you can find somewhere that sells just the clutch assembly and can get the appropriate tool to remove the pulley to get to the clutch. Try buying a repair manual and looking in there.
No, you don't have to replace your sink, you just have to replace the fixture's seals. That will stop the water from leaking.
Rather than replacing just the ball joints, replace the whole arm as replacing just the ball will more than likely not work. Use ball joint remover tools to remove and replace.
it would be best to replace all
Yes, just be careful not to scratch the crank journals with the studs on the piston rod.
Since it's the lower, I think you can replace just the ball joint. Most of the time the uppers are replaced by replacing the entire arm.
