When making a sharp turn my steering wheel made this popping pop once..the steering was fine but I am worried that it my be a serious issue
Its been making a loud knock from what seems to b the middle of the steering wheel, i cant feel it in my feet (or feel like its comming from outside the vehicle) just in my hands (the steering wheel) and it only seems to happen when i make hard right or left turns.
Knocking and popping and even some creeking when I turn the wheel. Doesn't happen all the time, just started happening a week ago. Had my car for three months now. Had someone look at it today, they suggested the steering knuckle. Ive been told it could be the rack and pinion. Yikes !!!!! to be continued....
knocking / popping noise and loose steering wheel. :( just had it in for the recall 18 days ago.
Now it will cost 1400$ to repair.
This has been happening for some time now. I first noticed it last year. There is a knocking noise in the steering column when I turn tight radius was sometimes. I didn't realize this could be dangerous! Now that there is a recall for power steering issues in 2008 - 2012 models it sounds like they should be extending this recall to 2006 models too!
When I turn slightly, I do not hear the popping noise; however, when the turn is sharp, it makes a popping noise that sounds like something is being dislocated.
I have not taken it in, yet, as it just started to happen.
popping and vibration during steering maneuvers - local Ford dealer quoted $1,200(labor and parts)to replace worn U-bolts, and perform necessary alignment.
Replace drive shaft. Also , while ignition switch& cylinder worn out& finally unable to start car...cost $485 for ignition switch etc.Replacement alone, does include tow cost...but, still seems very costly. Drive shaft will be another $285. !!!! So frustrated with this car!
Found the U-joint bad, took it to the dealer for repair. Ford has to have more Quality and Reliability to their cars. Repairs today are costly in this economy.
i fo problem and repaired it found the that ii repaired it for only 185.00 there is a hole in the firewall that made it very easy it only took 1.5 hours i am asc macanic they really took the people on job they shoud revoke that bills
