You are correct,
@nukegoat is having a hard time just reading the words I typed and not adding his perceived interpretation of exactly what I typed. At no point have I claimed the U-joints exploded.
Don’t assume you know anything about what happened here, if you truly would like to know specifics shoot me a PM and I am happy to chat with you, none of this is helpful to the OP.
All of the destruction in that incident was a result of traction and toque, the Spicer rep and drive line shop felt the parts shouldn’t have yielded and made it right, the gear manufacture also made it right and sent me another set of gears.
New gears same manufacture and new drive shaft made with Toyota slip yoke and Matsuba U-joints still going strong for 25000 miles. Replacement spare drive shaft with Spicer parts still sitting on the shelf.
Agree, they make the Spicer fanboys look good but in reality fanboys on every side are the same.
Can you share some of your Spicer science with us or are you just a fanboy and just keep telling us they’re good?
We are kind of going around in circles here, you said
And I replied,
So I’ll make you the same offer, if you truly care and would like to debate the details of what actually happened shoot me a PM and I’m happy to chat about it with you and we can let the OP get back to finding U-joints for his Toyota.
I apologize for the derailment of your post.
I will add this then I’m out. I was told beforehand by Kurt
@cruiseroutfit and Erik
@ginericLC both Toyota experts I respect to use OEM or equivalent drive line parts when I was building my Cruiser, they both told me that the aftermarket U-joints get loose and cause drive line vibration, this is exactly my experience. My drive line shop told me he would only warrantee the new drive lines if I used all new Spicer parts because he has had the best luck with them or I would have followed their advice from the beginning.
FWIW I only use Spicer joints in my 4400 car drive shafts and never had an issue, that car gets way more abuse than my cruiser.

Good luck!
