so my rear u joints on my drive shaft are on there way out. when i replaced them on my 4cyl 2wd s10 pickup the guy at the parts store offered me 2 part numbers one was the oem replacement and the other was from a full size blazer that were a heavy duty ujoint and the cross reference showed that they would fit. so my question is does anyone know if the full size universals will fit on an s-series blazer?
this probably should have been in the drivetrain category but i figured some of you suspension geniuses would have a better idea.

Its all the same people... It is always better to post where it is appropriate. I will move it.
How old was that s10 pickup?
Really, with practically all aftermarket u-joints being grease-able, a little bit of maintenance once in awhile and you should never fail another one, HD or not.
(BTW, always include your vehicle information)

Well, really, I do not see the need to throw something different in there. As I said, with grease-able u-joints, life (considering proper maintenance) should not be a problem. Choose a good brand and you should not have to worry.
Many of the name brands have a regular (non-grease-able) and a HD application. Information which can be found on any one of a number of parts store sites as well as individual manufacturers sites.
A quick look at the 534G application chart and you will see the cross over list. Any HD application for one will show up for all of the other applications.
But you could have found this same information using the same tools (google) I have...

A NAPA #PUJ 235 is their "off-road" U-joint and has the grease fitting located in the end of the trunnion bearing cap...no fifth hole in the middle for bearing lubrication. The type grease fitting used on the NAPA off-road U-joints requires a needle adapter to your grease gun which are also available at NAPA. I believe the grease gun adapter is in the Dorman-Help line of tools. If you and your vehicle is greased at a commercial facility, take the grease gun adapter with you and loan it to them because they probably don''''t have one.
The grease fitting in the end of the trunnion avoids a grease zerk in the middle of the U-joint and the fifth hole which weakens the U-joint and gives it a place to break. The last time I broke a standard aftermarket U-joint, it was busted in the middle where the fifth hole for the zerk fitting is located.
Dana Spicer does not make U-joints for NAPA anymore. Starting in 2002, NAPA U-joints are made by GMB-Japan (Gobal Management Business) The GMB part no. 215-3105. NAPA had to purchase from GMB because the American companies are either going "belly-up" or having their products made off-shore and repackaging them in containers marked "Packaged in U.S.A."
Besides being made in Japan, NAPA "off-road" U-joints a high quality products.

If you go to a comercial oil change facility, YOU will get a grease job but your vehicle won''t.
The grease monkeys down in the grease pit are afraid to grease cars. So few vehicles have grease fittings, they don''t know how to do it properly. The manager of one oil change and grease facility even told me that my 91 Blazer did not have any grease fittings. I said: "Oh, is that right?" I did not argue with him because a long time ago I learned to "Never argue with a fool."
The grease monkeys are reluctant to grease vehicles because it they do not control the amount of grease pressure they apply to the fitting, and they can accidentally blow out the rubber boots. They had rather just lie to you and make you think they greased your car rather than risk damaging it. I would wager that my 91 Blazer has not been greased but one or two times in 18 years although it has been through those commercial lube centers hundreds of times since my daughter purchased it new in 1991. Since she gave me the Blazer, I now do it myself with a hand operated grease gun when I change the oil. It is a dark and lonely job when you are laying on your back but someone has gotta to do it.

When those "strip-joints" first appeared in the mid-1970s , the grease monkeys stripped the drain plug holes out all the time. After about ten years, the grease monkeys learned that they do not need to overtighten the drain plugs to prevent an oil leak.
Now the grease monkeys overtighten the oil filters. They do that for two reasons: 1.) They do not want the customer changing his own oil. They overtighten the filter so only they can get it off with special tools. 2.) They overtighten the filters to cover their a$$ in case of a leak and engine damage occurs.
Many Wal-Mart stores and some oil change establishments will not change your oil if there is any sign of an oil leak under the car. That is because they fear if you ruin or severely damage your engine by running it out of oil, you may blame them for it in a law suit.
In the same vein: Most transmission repair shops are reluctant to flush and replace the transmission fluid and transmission filter for the same reasons. A friend of mine owns a small automatic transission repair shop and he will not flush or change anyone transission fluid. When someone asks for that service, he merely tells them: "The transmission fluid never needs to be changed and the filter will last for as long as you own the car."
He thinks a person wanting their transmission fluid flushed or the transmission pan dropped and the fluid replaced could be running a scam in order to get a bad transmission rebuilt free of charge. The scammers would say: "You sabotaged my transmission because it broke right after you changed the fluid." Lawyers have ruined the automotive repair business and made it so people cannot afford to have ther car worked on by repair shops. LOL
