Outer Limits 4x4 Board

Well my mate has a 2.8 diesel Hilux with an aftermarket turbo.
There's been this bearing type noise that he's traced to the vacuum pump attached to the alternator (alternator has been rebuilt).
He hasn't pulled it out to look at it yet but rang Toyo to get a new price ($870 + GST ).
Are these things rebuildable ?? Or is there an alternative source for rebuilt/changeover units.

Thanks, Frank.

strip it down got nothing to loose most times anything repairable
never go toyo genuine too frigen dear shop around first

They are expensive!!!

You best bet would be to source a 2nd hand one from a good wrecker!!!

Or you can try and replace the bearing, they are fairly simple to pull apart!!!!!

it cost me 100 bucks for a full rebuild on my crusier alt with vac pump.

Mine just cost me $400 to get it rebuilt including Labour
