Thread: Rotoflex or U-Joint conversion

Oddly enough, a few of us (Redback, DiscoWhite, & p38arover) were discussing this over lunch on Sunday.

As Phil (Discowhite) pointed out, if the Rotoflex does fail, at least it will still provide drive and you can replace it on the roadside without special tools.

Disco2 geometry is way different to the other land rovers and the rotoflex isn't significantly affected by lift such as in the others.

The advantage of changing the rotoflex out for the uni is that it is a much stronger setup and shock loading wont induce a failure.

The disadvantage is that you lose the "cush" absorbtion of vibrations and shock loadings.

In my opinion, if you are not breaking rotoflexs in a Disco2 and if the 3 bolt flange is compatible with your aftermarket pinions, then don't swap out the rotoflex. If you are breaking rotoflexs or running pinions with the big nut on the end, only then swap out the rotoflex for a uni.

I swapped mine out for unis.

I agree with Slunnie, the only reason I changed mine was because I had a locker fitted (it was recommended I do) otherwise I would not have changed, I had 130,000k on mine when I changed, still looked brand new.

Its clear from the replies that there's quite a range of experiences. In my case, I could not install the spare I was carrying as, when it failed, it sheared 2 of the high tensile bolts (I didn't carry spares of these) and mangled both the shaft flange and diff pinion flange.

Interesting, I Will be adding a rear locker at some point, so may do this conversion then if the advice goes that way

Thanks for all the replies so far guys.........
