I AM WORKING ON A 99LESABRE 3.8L. CUST COMPLAINS OF NOISE IN
LFWHEEL WHEN TURNING RIGHT. SOUNDS LIKE ROTOR HITTING THE BACKING
PLATE. HAVE CHECKED AND REPLACED EVERYTHING ON LF SIDE TO
INCLUDE ROTOR PADS BEARING AND AXLE. OBVIOUSLY I BENT THE
BACKING PLATE BACK NONE OF THIS HELPED. ANY IDEAS?
JK:
Have had strange tire noises, but make sounds turning either direction.
As long as you replaced the whole axle. Have had inner tri-pods make noise on that axle.
Will ask SF our trans guy on mon. if anything with the trans.
How about this, have had a few loose starter drive gears slide into the flywheel when
making rt. turns. In an open area, drive and keep wheel turned while it is doing the noise,
then shut off engine and see if noise stops (dont turn key all the way in case steering
wheel locks).

Noise in the Front End Of My Buick
Question:
2005 Buick Lacrosse
sometimes when I accelerated from a stop or just to get into traffic, the engine will
increase in RPM. The engine won't die completely, but will not accurate or increase in
power. The engine has eventually stalled & will restart. Let the engine sit for at lest 5
minutes & the engine will restart & run like there is no problem. This is an intermittent
problem. Car will not stay broken long enough to be diagnosed proper. There is never a
check engine light & no codes are stored. One time a cat converter code did set & the
converter was replaced. This did not solve the problem. The engine stalled the next day &
died. It restarts a few minutes later & I limped to the dealership. Nothing found & car ran
well. The engine stalled again 3 weeks later. Driving about 25 MPH, engine began died. 5
minutes later the engine started up ran well.

GM Tech JK:
This really did sound like a feule pressure problem, but that is not the case.
You may have a crank position sensor acting up, or possibly a wiring problem somewhere. Moving
harnesses under the hood while running may cause it to act up, or correct itself.
Grounds on the engine / trans bellhousing may be loose, or even a power feed problem at the underhood
fuse box. Either of these would most likely not set a check engine light or codes.
Move those harnesses around, pull on the fuse box and harnesses, check the ground, and see if this helps
