NAPA propshaft

[InvisiBill]

After looking at the options and hearing from Keith about his, I've pretty much decided that this is a good way for me to go, as it doesn't cost much more than a Dynotech rebuild, and it permanently eliminates the boot problems. The shafts by Brandon and Al seem to be a bit excessive, since an Ultimate is probably the biggest mod I'll ever do.

Keith's shaft is a Raylok 50-357, as the pictures show. Apparently that's an old number, and they can't just cross reference it to a new number (part changed, etc.?). They found a 12-352 for $261, but that was under Sonoma 4x4. Would a regular Sonoma shaft work? Can anyone say for sure if this is the same part Keith got, or what the new number would be? I know some people use the Bravada shafts...

I'd like to replace my propshaft before it blows up and trashes the rest of the truck in the process, so any help at all is appreciated.

bill, just take yours in and get it rebuilt.

I waiting 3 weeks on one from NAPA and it vibrated like crazy. With all the headached involved, I would have Dynotech rebuild it or buy a new one from them. They also offer a beefed up unit. It has a bigger double cardan. That is where the catastrophic failures usually take place. It is from a Bravada but they shorten the shaft to fit our trucks.

Hi Bill, I am just releasing a new shaft today. This is a slip spline joint with a much bigger double cardin joint. The shaft will sell for 490.00 and will handle high horsepower with no vibrations. Please email or call me for more information.

Blake, what part number did you get? Keith said he's had absolutely no vibration problems with his, and would recommend it to anyone as a stock replacement.

As I said, I don't really plan to do any real mods to the Sy, maybe just a little tweaking. As such, I'd rather not pay twice as much to get a shaft I don't need. After reading some of the comments that most of the boot failures are due to neglect/abuse, I eased up a bit on the idea of stock shaft rebuild. Still, I'd like to get rid of that boot setup if it's not really needed, and never have to worry about it again.

I had the local driveline shop do mine. They charged around $130 to do the front part into a splined joint. Then later I broke the rear two U joints. They did those for $185. If you have a good driveline shop nearby, it doesn't hurt to ask. HTH,

Is our shaft anything special, as far as having a local shop work on it would be concerned? Most of the places around here would be geared toward big 4x4 stuff... Like I said, I wouldn't mind keeping the stocker (or equivalent), I'm just wary of letting those hicks touch anything I'm going to put on the Sy... Or anyone know of a good shop in Michigan, preferably around GR or Detroit?

The shop I went to does a ton of 4x4 and semi-tractor stuff. They know exactly what can hold up to what and they were pretty damn fast at getting it done. I don't believe anything is "special" on ours except maybe it's balanced abit faster and to a more exact tolerance than most. You can always try your local shop and get them to have a look. My shop quoted me on the exact dollar amount and delivered right on time. HTH, Christian
