Outer Limits 4x4 Board

I keep blowing uni joints in the rear of my rear shaft one closest to the diff. Its a 89 serria with twin lockrites and low range gears, I have built the engine up to have torque and i run a webber. what can i do to stop blowing unis?????????????

My mates tell to stop doing hellies, but its fun

same.

u lifted?

and driving style doesnt help

ever balance ur shaft after changin unis? and stop doin hellies

Greasable Uni's will last longer than non-greasable IF you keep them greased.
And ease up on the (totally optional) hard driving style.

or up grade the unis

but yeah maintenance and stop doing hellies

was a time when a large bearing retailer was listing 1.0 litre unis for 13's. will fit but won't last. my rule of thumb is i now order vitara uni's for 1.3's. that way i don't end up with the wrong ones.

just looked under my car. drove home from fraser island the other no hellies only driving and uni has play in it. I am lifted but only 2" spring under, tried greasable and non no difference

Sure its Uni? and not diff backlash?

ALso that uni with play in it. is that a new uni before the fraser trip?

One last, are u running soft springs with axle tramp ruining the unis.

You need a mechanic or driveshaft specialist to look over your car - Even in cars abused off road the unis should last well over 12 months, especially with the tyre size and suspension you're running. I guess you have something bent/damaged/ out of phase. It's going to be too hard to diagnose on here - take it to a specialist.

bent ear or ears on the dshaft or yolk would be my bet.

Get a new second hand shaft and try that .. bet you have no more issues

Im old whats a hellie?
Ive run 31s with welded rear on the street twisted axles unis fine,
32s locked gave it hell off road unis fine
33s with toy driveshaft unis fine, so you sure its unis?
All these with spoa so step angles so you sure its unis?
If it is maybe upgrade to toy drive shaft, not a hard mod and bigger unis.
