We have a 2003 Alero. The bearings keep going on

Yeah they are. But I wouldn't put a used crankshaft in a vehicle. Way to many variables by doing this. Get a remanned with the bearings.

Sounds like the passenger side hub and bearing assembly has worn out. A new one is $60-80 if you can fix it yourself.

BAD BEARING OR WORN TIRES

sorry but time to visit the transmission shop. the only thing you could try first is Lukas Transmission oil sold at parts stores one quart only. make sure you get the oil for transmissions and not the crankcase.

Have a shop look at it. It may just be a failed wheel bearing. The bearing will leave you stranded if it gets bad enough and cause more damage.

tires maybe

TEMP GAUGE SHOULD STAY IN MIDDLE.IF ITS MOVING UP A LITTLE CLOSE TO RED.CHANGE THERMOSTAT AND RADIATOR PRESSURE CAP MINE RELATIVE CAR DONE THE THE SAME.I REPLACED THEM BOTH -.WARNING IF ITS YOUR FIRST TIME LET A GARAGE DO IT BECAUSE YOU GOING TO HAVE TO TAKE THROTTLE BODY OFF.TO GET TO THERMOSTAT.THEN COOLANT SYSTEM IS GOING TO TO BE BLEED.TO KEEP ENGINE FROM OVER HEATING.IF YOU BEEN USE TO WORKING ON CARS. ALL IS GOOD.

Use Valvoline 10-30. Manufacturer Recomended.

Hi, there I solved it myself turns out it was the driver front Abs sensor. the bearing had to be replaced because the Abs sensor is build into the bearing.

With any manual transmission you shouldnt just go from 6th to 4th bc it is bad for the transmission, if i am in 5th gear and i want to go into 3rd i always go from 5th to 4th to 3rd as a preventative maintenance. If you have a defected transmission you should be able to get it warranted by the bmw dealership you bought if from though.
