U Joint flange failure

[fe sus]

While replacing my shocks I noticed something off...

The truck is at 270k and I'm trying to decide what makes the most sense. U joints and replace the flange? Or just replace the whole driveline?

That crack is on the U-joint cup and not on the flange. Stay with OEM U-joints and never anything else. GMB and all others are junk.

Buy a new drive shaft-

By the time you buy new Toyota ujoints (don’t use aftermarket here) , have them installed ( which often times is poorly done) , then have the drive shaft balanced youre not far from cost of new ( from one of the online dealer sites).

Do you need to rebalance if just replacing the ujoints? I would have thought they are inherently balanced on the center of rotation, but I’ve never changed them. On my short list.

One shouldn't need to rebalance if the u joints are property installed per FSM. For the OP, there's also the slip yoke for consideration. If that has excessive slop/wear I'd get a new driveshaft. Otherwise new Toyota u joints and keep on trucking.

No, you don't have to balance the drive shaft if you are installing OEM U-joints. I have changed U-joints on our hilux, 4runner and few other cars and no vibrational issues.

As other said no need to rebalance. But in case you do replace them: mark very clearly the positions so you put everything back in the same place.

I think I'll pull it when I have some time and check the slip yoke.

Looks like ~$75 for the front OEM:

Is the rear different?

Also, what about a double cardan? Anybody used one of these?

Toyota Land Cruiser Rear Drive Shaft, Double Cardan

Toyota Land Cruiser CV Rear Drive Shaft This is what you need if your Toyota Land Cruiser is lifted and you are experiencing vibrations due to increased angles. Also a great upgrade for Toyotas that came with a stock double cardan drive shaft. This is a rear shaft only and can be made any length...

Do you need a DC driveshaft? With a well balanced shaft and new joints, should be no need.

Looks like front is oddball for early 100/lx470, rear is standard.

I don't need DC, just wondering if there are benefits for a truck with a mild lift? Never used one before and just came across it on that website.

 

[GerLC100]

In case you're heavily lifted the driveshaft angle will eat up the joints quickly. So you'd add a double cardan to cut the angle in half per joint and reduce wear.

I was chasing a vibration on the rear driveshaft and changed the u-joints. The vibration worsened! It went from vibration sometimes to vibration all the time. Had it rebalanced and all was fine. Perhaps the loose joints were masking the vibrations! Ha.

Hey there

Yeah it’s a good idea to true and high speed rebalance.

l had a double cardan on my HJ47 which needed the sliding shaft repaired, l opted for a complete Fuji shaft to replace it... cruiserteq can supply the parts if you decide to use a cardan...
