Well, funny (long) story.
After fitting new front shocks, springs and upper arm bushes, I took the ute to the local steering specialist to change the lower arms with the used bare ones I supplied, and asked about using lower front poly bushes, and they said they use them a lot, but only use Superpro.
I showed them the lower front Nolathane bush, and they said they
should be OK but they have never used them!.
I got a call from them saying they couldn't get the Nolathane bush to fit back into the mount brackets saying it was too wide ??
So in the end they supplied and fitted a Superpro bush .
They also said that Superpro have a lifetime warranty !
After all this hassle the lower arm bushes and ball joints were still in fairly good condition, even after 175000 km's
Even the wheel alignment wasn't that bad, and that's after nearly 100,000 since the last alignment !
All this work was done mainly because the front tyres scrubbed out badly on the inside, and also I wanted to to raise the ute ( replaced superlow springs with low springs ) due to our crap roads.
But now I blame most of it on poor quality tyres
