Can I use a 2004 Chevy trailblazer front differential to replace my 2005 awd Buick Rainier front differential

Speedometer does not register how fast you are going or if you are going maybe 45 mph it will say you are going 95-100. Also fuel gauge goes up and down when you are driving. The passenger side mirror will not stay set

My mechanic says it is because I have to buy all new tires and be put on at the same time??????? Help P. S. It shakes too???

All vents blow air into the cabin with exception of the ones actually on dash facing you. Even the ones facing the door by Windows work. Any ideas on issue or location of where to look??

Labor time and cost for rear suspension conversion?

there was only 2 inches of smow

I have checked all fuses, and read everything I could about it and have figured nothing out. All speakers are hooked up as far as I can tell.

it sounds like its rubbing. I have a 2006 buick rainier awd

battery dead, wend I jump it , wont start, code p2101

5 or 6 years ago wife had this happened, they replaced a fuse under the drivers seat. where and how do I check this?

Sometimes the sound works, could it be a loose connection? Is there a wire scamatic available?

It looks like interior lights maybe flickering a little.

All lights come on in dash.

Is this expensive to repair? When I am driving in a straight line, it is ok. It hasn't effected mileage. Every time I try to make a sharp turn, it seems the wheels jerk. Is this going to be an expensive repair? Another issue is the rear air shocks loose air. When car is running, it seems like rear end goes up again. I never hear the load levelers working anymore. Thanks for your help. I'm a 74 year old female widow and need some advice. Thank you for your help.

Sometimes rear air suspension goes down overnight and will fill back up when vehicle is started. Compressor and air bags work properly and can find no leaks.

When I step on the gas, there is a high pitched sound that comes out of the speaker. Sometimes it is a loud buzzing noise and if I turn off the radio then it is quieter. It doesn't happen all the time.

on occasion my 2004 ranier rear end sags to the ground.......usually the air compressor will blow up the suspension bags when ignition switch is turned on, and it will be fine for 2-3 days, then will happen again. I do not believe the air bags are leaking, since they stay inflated for days after the problem, and the air compressor is functioning as well. Is there a valve between the air compressor and air bags that coule be malfunctioning? as expensive as repairs are for this, I want to fix the right thing/ please advise.

you can hear very low but can't turn it at full volume it is not any louder then all the way down.
