: Generally, a whiny noise is caused by lack of proper maintenance and may indeed be effected by inadequate or improper lubrication. Unfortunately, the manufacturer has yet to provide a proper service manual including maintenance schedule for the spouse. Therefore, we must apply known procedures, as best we can, to the maintenance of the spouse.
: Intake and Exhaust:
: We well know that improving the intake and exhaust volumetric efficiency can well improve performance, especially at top end, however the lower end can at least be supported if not improved. However with my spouse, their seems to be an association with increased intake performance and an increase in rear end ratio, with no corresponding increase in output. I am working on this, but had the spouse been a Mini years ago, the increased volumetric efficiency has not yielded a fast mini, but rather an Expedition. Wish I had a manual.
: Body work:
: Not possible without extreme measures and even more extreme insurance. Major body damage may be repaired, however the expert shops don't seem to be able to return the spouse to original specs. Functional, however bulging and major frame expansion do not seem repairable.
: Timing:
: Aligning timing with the spouse grows increasingly more difficult with age. In my experience this is usually repaired with the replacement of the timing chain, however timing changes with the spouse are more difficult to diagnose than with mechanical vehicles. Interestingly, derivatives of alcohol are useful in improving intake performance in our trucks, however I have found that when both the driver and spouse are treated with alcohol, that timing can be aligned more readily. However continued treatment in this manner will most definitely effect the rear end ratio and frame expansion of the spouse. I need specifications.
: Upgrading:
: Similar to our trucks, there are two levels of upgrading. 1.) Modify the existing to our satisfaction or 2.) trade in for a new unit with improved specifications. #1 has no manual so we are on our own, #2 is well known (editor would not allow the word d-o-c-u-m-e-n-t-e-d) and is way too expensive for the majority of us.
: Bleeding:
: On our trucks, gravity bleeding can take several hours with all bleeders open. You can't trust anything that can bleed for a week and not die.
: Can anybody add to this list? We could at least start the manual.
: ROTATION:
Although rotation is recomended on some models. the current model that you have may not be applicable Like was specified before no manual was given to determine "good" and "BAD" rotation times.
IMHO "Play it by ear"
: LUBE JOBS:
Lubrication is a very integral part of "WHINEY NOISE" reduction. A synthetic blend of proteins is generally needed "as per model" (some tend to want it more than others)Without proper lubrication, recent models have a tendency to go from "WHINEY" noise to outright "SQUEELS", and "SHIMMY'S"
: LOOSE AND TIGHT FEEL (IN TURN)
It has been noted by the inventor our complaints about "TIGHTNESS".
As far as I know; after a few units have left the original model, things seem to "LOOSEN" up a bit
"THERE IS NO FIX FOR THIS", just have to live with it!
