U Joints
I am rebuilding my differential and would like to replace all the u joints on the half shafts and drive shaft while I have everything apart.
Iam wondering what u joints are good to use???
I would like to get something that will be stronger than the stock ones.

Exceptional choice 
Why???? Cause the better they are the longer they will put up with abuse before they are out of spec or simply fail. Thats common sense really. So why not??

I went to Lorco and bought solid U-joints. I don't remember the brand, but they were a well know manufacturer and were in stock and a whole lot cheaper than spicer.

Brute Force = Brute Cheapness, please don't use them. Get the spicer cold forged non-zerk units with the coating that is compatible with our aluminum halfshafts and driveshafts.

Are all 6 the same? Anyone got the part number(s)? Napa and O'Reliys both said they don't carry Spicer. Auto Zone and Advance both carry China-crap. Guess I'll have to find the Spicer joints on line, but that is near impossible without the part number.

Take the half-shafts and driveshaft to the Driveshaft place, they'll put Spicer joints with the right coating for aluminum shafts. Also, they'll use synthetic grease. Have them check balance on the driveshaft while you're at it. Mine was a bit off...

Here are the "Spicer" numbers for the coated type for use on the aluminum Corvette shafts. Driveshaft (1310 series)....SPL22-2X. Halfshafts (1350Series)....SPL30-2X. Here are the old numbers for the above U-joints, Driveshaft....5-786X. Halfshafts.....5-800X.
Best place/best price I ever got on these Spicer u-joints was from a "heavy truck" parts store. These are the best you can get, non greasable and well worth it.

Here are the Neapco "Brute Force" numbers, Driveshaft....1-0626BF. Halfshaft....2-0617BF. These are also the coated type for use on aluminum shafts. Please note that these U-joints are listed as greasable. I think the grease (zerk) fitting is in the end of the cap not the body of the joint.
The only other U-joint to consider are the Precision "Super Strength" brand but I don't see a listing for a coated cap type to be used with aluminum shafts. Here are the part numbers for the noncoated type, Driveshaft.... #280 (greasable/in cap zerk fitting). Halfshaft....#232 (greasable/in cap zerk fitting).... #231 (non greasable).
The main thing to keep in mind is the driveshaft uses a 1310 series size and the halfshafts use a 1350 series size. The caps on the u-joints should be coated to help prevent galvanic corrosion between the dissimilar materials.

Go to Tom's Differentials and order Spicer cold forged w/o zerks, that is the ONLY brand you ever need to put in.

I have all three shaft out right now since I'm installing a new engine, clutch, and replacing every bushing I can find. No better time to replace the u-joints.

U-joint can fail for reasons other than breakage. In fact, for every 1000 U-joints that fail, 9999 of them fail for reasons other than breakage. In those 9999 cases, a stronger U-joint will not last longer. That's why I asked if he's breaking them (or, just wearing them out?).
"Better" and "stronger" are not necessarily synonymous. You can have a U-joint with the highest tensile strength of all, but if the needles fracture, or dry/wear out from lack of lubrication, you're still gonna' have to replace it............
Maybe "stronger" and "better" are the same to you. If that's the case, then what I said above probably doesn't make much sense....and I apologize for taking up so much of your time.

You knew exactly what i meant mate. Its common sense. Read the part where i say "out of spec" and have a think about what that means..... I never mensioned 1 single thing about breaking anything. Out of spec/simply failing and breaking are not necessarily synonymous.
Id heard exactly the same thing mate yeah

When the PO said he's looking for something "stronger", you assumed he meant "that wouldn't wear out so fast"....and maybe he did, but that's not what he said. So I asked for clarification.
You might be a mind-reader, but I am not.
He said "stronger", this tells me he's experiencing problems with a weak part that is breaking.
If he'd said "longer lasting" or "more durable", then he might be talking about something else entirely.
Regardless, I think several people have pointed him towards the items he is searching for. So,

Case, Case, Case...you assumed he wanted a "durable" U-joint when what he said was...
As you said, "durable" and "stronger" are not synonymous.
Any time one hears "It's obvious.", you know it's really not.........
Give up, mate, you cannot win this one.... ...but thanks for playing!
