replacement whistling turbo

[dmetalmiki]

Any information Anywhere about whistling turbo repai or replacement? We recently purchased two (suposed )whistling turbos specifically asking for units of that type. BOTH new turbos where NON whistlers.. despite the company perpoting them so to be! and they where expensive. Is there and DEFINING part# or serial# i.d. whatever to facillitate the CORRECT replacement type to orriginal "noisy" spec. Replacent units in U.K. and continent BY LEGLISLATION have to be QUIET!..SO just how OR where and at what price can we replace our worn turbos (whistlers) for M series trucks that WHISTLE as LOUD (or louder!) than our orriginal worn out units? perusing all and any T.M. mags and write ups reveals no information as how to obtain an orriginal "noise to type" and knowledge or dfining information appreciated. (THREE units now sought here in U.K.)

The "C" (whistler) and "D" (quiet) turbos have different part numbers, but they are not, to the best of my knowledge, marked with a part number or any other identification to be able to differentiate between the two, you have to look at them to tell which is which.

There are two readily visible landmarks to identify which turbo you have. First, the exhaust side of the "C" turbo is tapered from top to bottom giving it a snail like look, while the "D" turbo exhaust is fatter and has a uniform width from top to bottom. Second, the exhaust and intake sides of the "C" turbo are joined together externally with a "U" shaped band and clamping bolt, while the "D" turbo halves are joined together internally with bolts. The attached photos clearly show the difference.

I took truck out to check turbo :n applying full lock.CRACK BUMP WOBBLE! my son shouts the (blooming!? or something similar!) AXLE jumped over 3 or 4inches?? so I get him to drive it the OTHER LOCK..and sure eniff CRACK BUMP over go the forward two wheels untill they stick out of line 4"!! going the oipposite lock to that results in MORE cracking bumping and assorted noises untill the forward rear pairs have now shifted across from out 422 to straight to 42 the other side!! SO..I teks a look under.. AND YES THE..F....pra... HAS (the) AXLE CROSS TUBE WELDED to the outer housings!! (just inside the srprings) where it comes out of the bush and goes accross the width of the truck. (and yep..)HOW does it move longtitudaly?..(bumps undulating terrain)etc)..QUITE!! so now the whole axle jumps out of line when steering is applied in that direction.(runs IN LINE in straight ahead travelling )..so ANY IDEAS BOUT THAT?..I gotta get my manuals back I lent out..cant quite figure what holds the axles from moving out on turns..UNLESS the bushes where the tube enters the housing IS SUPPOSED TO BE (tight/jam fit..locked in??)..again any knowledge appreciated..
