OK then is there someway to check this out to see if in fact it is the compressor bearings??? This thing is at the back of the engine almost up under the dash---with out taking all the intercooler pipes etc off is there a "simple way to check it out"??? also how loose or free should the wastegate valve be? Same ?? on the impeller ??? like can I move it(wastegate) back & forth with my fingers or do you have to kinda pry/move/turn it with a pliers/small screwdriver???? Thanx for the info this is all new to me do not want to spend a THOUSAND bucks to fix something I propably can do myself--Comp 387

You should be able to put two fingers on the impeller nut and try to wiggle the impeller. There should be only a very small amount of play in the shaft. Very, very minimal. Any more than that and you have a bearing problem and risk terminal damage. If you are having a lot of noise it might be too late now. The impeller will wear away the housing and destroy the impeller. We probably should have asked you before this.... what is the combo you are working on? If it is a Chrysler product it is usually easier to pull the head to replace the turbo should it prove damaged. Jim

OK ---got to work on the truck over the weekend---took off the hose from the air filter to the inlet on the turbo and I can see where the impeller has been rubbing on the OUTER edge of the impeller probably on the inside of the case---now next question is is the case destroyed or can I just replace the impellar and install new bearings and be OK? I have not gone any further on removal/disassembly at this point waiting to see what I need to do next OR do I need to I swap out the WHOLE unit for a rebuilt one?--Have a guy/friend in my area that is a whiz with the V-6 BUICK GN cars does the whole hop up routine on them so I imagine a turbo is a turbo!!! If he can work on the Buick stuff a Ford should not be any problem- ---Really appreciate all the answers you guys have given me---Gonna talk to Ford see if they will help any seems they had a TSB(technical service bulletin ) a while back on the bolts loosening up and destroying the impellers maybe I can get them to cover some of the cost?( ya right) Comp 387

A turbo spins over 100,000 rpm so it is precision balanced. Don't just try to replace bearings and hope you get the torque right on the impeller nut. Get a quality shop to rebuild the turbo. High Tech Turbo in Murray UT and BD Power in Abbotsford BC are two sources. Your compressor housing may be reusable if not badly worn. You will need a new wheel. Don't keep running it. If the turbo blows up, you will spend a long time cleaning out the pipes, intercooler, etc. and hopefully none of the shrapnel will make it all the way into the engine.
