Replacing 100 Series Live axle front end bushes

The worst problem with the poly type is they limit sideways flex which results in breaking the rear section of the diff housing mounting ears. The original welding can be sus in that area so check thoroughly.
Yes, I am speaking from experience - failure in the North Simpson brought out the bush welding skills as diff oil was leaking too. Use genuine for sure.

Not quite so, the bushes, whether rubber or polyurethane are moulded into an outer metal retainer which is pressed (interference fit) into the arm holes. They are not a loose free fit like shackle rubber bushes, so mud and grit are not a issue with the bush and the arm.

My experience with 105 series front control arm bushes is that the rubber ones last longer than the urethane ones in a more extreme/articulation environment.

After 167,000km, I am onto my 3rd set, 1st set original rubber, 2nd set OME urethane..which cracked annd allowed the innner steel bush to become free, and the 3rd set are rubber and doing ok...from ...and I hate to say it...Pedders.

My 2nd and 3rd set are also of the + castor offset design, which by having the inner bush offset in relation to the outer does not enhance their life.

Willl everyone also remember that the live axle Landcruiser is a 105 series, not a 100 series.

I'd be asking the same question. Most common cause would be freeplay in the wheelbearings.
