Hi my check engine light came on last night for the first time so i took it to auto zone for the codes there P1173 and P0157 what do they mean someone said 02 sensors and also i just noticed that when i start driving around 30 mph the front end and steering wheel starts to shake like a shudder then it disappears once going 40 to 45 do you know what this could be?

 

mileage on your truck? Might put your year and mileage in your sig so people dont have to look.

 

Stop driving your truck, right now and send me your tele number. Among other things, sound like you are about to loose your front drive shaft.

 

its got 123,232 miles on it

 

Get the front end checked out today, you may have worn ball joints, loose tie rod ends, a tire out of balance, a bad tire, could be anything, and anything that has to do with steering is a no mess around thing because your safety and the saefty of others is on the line.
