I just replaced the one on my Cummins this weekend. Put in new injectors and 640 miles later lost the turbo. Its an easy fix to do yourself. Got the reman turbo from Freightliner for $622. Seems like the shops always over price them...big time. I gotta completely echo what Bob H said. I didn't bother checking mine when I overhauled the engine at 964,000 and put it in this truck. I've got about 79,500 on the overhaul now. I should have used the old dial indicator on the turbo.

Dial indicator isn't required for the quick checks you should be periodically doing. Try to wiggle it with your fingers and give it a spin. If it has a questionable amount of movement then bust out the dial indicator.

Default brand

I put a brand new garrett on my Cummins and it did a great job. I did not need an exchange and it was half the price of the Holset. As far as installation the most important thing to remember is to prime the oil inlet so it's well lubed when starting. I put oil in both the supply and return sides (of bearing) and rotate rotor to make sure the oil gets in there good. Also when you first start engine let it idle several minutes before reving up or driving. It's a good idea to let the engine idle down for a few minutes after parking to allow the turbo to cool down(after running hard) that will help increase turbo life

I'm the preventative maintenance kind of guy. so should I replace or just keep what I got? also.. I remember turbo's on the 500 detroits going out like crazy a while back. I believe it was the turbo mfr & not detroit diesel. what was the failing brand & the good one?
you should always carry the rubber hose and wire with you, if it gets a hole in it, it can cause serious problems and is very expensive to have fixed on the road,you can change it yourself in few minutes provided you have one with you
