My fiancees X has a bad squeal from the engine on acceleration.
i told her to switch of the AC/heater. it worked....So could anyone let me know what's the fix?
Alternator belt?
Tighten alternator belt?
or something worse in the heater/AC?

 

Did you try turning it back on afterwards? What happens to the rpms before and after shutting down the climate control?

 

i'll find out in a couple hours when she gets home

 

i got the dreaded call
she broke down

Her mechanic friend told her the rear transaxle was broke...CV joints?
What kind of repair cost am i talking about?

I guess it wasnt the alternator afterall. must be coincidence that the noise died down when she turned off the heater.(She said the noise was back this morning)

 

If its the 2 outer CV joints they are £148 each fitted in the UK at a Jag specialist charging £35/hr.
Possibly less I would expect overin the USlike just about everything elseautomotive.[&:]

 

Heres the price for the part on a pdf document that I have...may be out of date since 2005 though:-

Then again it could be something else.

 

If the noise is back and it changes when a/c is turned on/off then I would suspect bad compressor. The rear halfshafts are just coincidental and would make a different noise.

 

Keep us all updated...

 

Got the results
It wasn't even the rear!!!!

Both front driveshafts (L & R) are shot
