Topic: How strong are toyota drive lines?

[toy87]

I was hoping for a little experienced advice. How well do the Toyota ujoints and drive shafts hold up. Will they handle 35 lockers and a mild crawl ratio about 100:1. I know i could put 1310 half ton shafts and u joints or i could go with 1350 one ton drive shafts. I had Blazer with a 400 V8 with a 1350 rear drive line and a 1310 front drive line and did not have problems with either. What is truly the difference, does it really matter? What makes the extra money worth it? thanks for any ones advice

I've always used stockers and haven't had a problem.  I run dual cases, lockers, and 37's with no trouble.  The toyota ujoints and shafts are actually really overbuilt for their application....

i'll tell you after an after-midnite new years episode in my buddies yard that toyota drive lines are rad.  my rear driveline stuck on a granite fin that was between some big boulders i was crawling over. basically the rear half of my rig had all its weight (including a 250+ pound camper) resting on the dirveline and my locked rear tires off the ground and locked front tires spinning. the driveline was spinning on the fin before i realized recovery was gonna have to wait until morning(afternoon).  after my rig was off, there wasn't even any grooves on the driveline where it had been spinning on the fin and the u joints that had hit the fin were golden too.  the driveline was as straigt as stock even after some friends attempted to bounce me off!        i was amazed.

I ve sheared the bolts off mine before but never broken a driveline

Thanks for the info fellas i appreciate it one more thing to take off the upgrade list.

Yup unless you SLAM down on a driveshaft while under heavy throttle a stocker will survive just fine.

i have riped them in half with my stock truck but i can break wierd stuff i also beleve thay bolth had dents wich is bad

I have seen them turn into prezels on the trail.  But toyota u-joints are supposably rated as 1-ton i have heard.  So you probly wouldn't break one of them.  But the drivelines can be strengthened.  Buti have slid all over stuff with my rear driveline and i only see the marks from it but no dents.

jess at high angle drive line rates a toy cv as stong as a 1410 u joint. a standard toy u joint is about the same as a 1350. jess swears by them he even runs them on his truck witha 454 making like 500 hp with 38s and a fullsize.

Of course, the quality of the u-joints that you are running is also an issue...Spicer are best, I think, although I have the heat treated NAPA u-joints and haven't had a problem.

[Rockcrawlintoy]

spicer joints for a toyota    the best is to run toyota u joints. i run some cheepo one on the front and have nto had any problems as of yet

actually spicer makes good joints regardless.  i think the toyota ones are 1510x joints, or something like that

i run cheapies in my rear driveshaft, haven't had any problems(other than it needs balancing)
