Evening all,

Time has come to replace the shackle bushes in the chassis on my 1970 88" 2A... Was wondering if anyone has fitted the greaseable ones from Great Basin Rovers, or something similar.

Apparently increase articulation, improve ride and last longer?

Over to you lot . . . .

Andy.

Greaseable shackle bushes were obsolete in the 1948. They do not reduce friction - the rubber in silentbloc* bushes does not limit articulation or introduce friction or limit articulation, as the effect of any shackle bushes on these is negligible. Any effect on ride would be that the rubber bushes would be better due to the cushioning effect. And, properly installed, silentbloc bushes are long lasting compared to greaseable bushes, which have a history of wearing because they do not get greased!

I fitted poly bushes to the chassis on my IIA - mainly for ease of replacement. As poly bushes work in a different way to rubber bushes, you need to use a generous coating of grease/anti-sieze when installing. Greasable bolts can be a good idea if fitting poly bushes.

For rubber bushes - see JD's comment.

I would never go back to rubber - too many poor quality bushes on the market - and Super Pro bushes are as good or better than any rubber bush IME.

I made up a full set of greaseable shackle bolts when I fitted parabolic springs. This was mostly due to the pain and suffering resulting from removing/cutting out frozen bolts.
I did it only to never have a problem removing them in the future.
I can see no advantage in suspension wear, use, travel etc as the rubber bush inner tube is bolted up tight between the shackle plates.
I also am running poly bushes in the para springs as getting rubber replacements was an issue, these are a two piece setup and having the ability to pump in fresh grease to push out contaminants is a good option.
I used high tensile bolts and bored them out , tapped ends for grease nipples and have two outlet holes lining up with the middle of the bush.

And so much easier to replace.
