Quoted From BigC:

The ball joints and/or wheel bearing would not expect to make any noise while starting the vehicle up. Typically a wheel bearing will make a “growling” noise when it starts to go bad. This “growling” noise is usually speed dependent as well. So, even at faster speeds, there would usually be some type of indication of noise for a bad wheel bearing. A loose ball joint would provide “play” in the tire. Again, if the same knocking noise occurred just during start-up, I would tend to rule out the ball joint.

Given the relative age and mileage of the vehicle, definitely see what the dealership says. Any concerns or issues should be covered under warranty. I would gently still pursue a loner/rental vehicle. While the vehicle was not purchased at this Ford location, you as the customer still want to experience a great relationship with this Ford dealership. I have found that being patient, polite, and courteous always go a long way in the end. Remember, this dealership will want to service your vehicle after its warranty is up. Obtaining a rental car will help set a great foundation for you with this Ford dealership and help to establish a long-lasting relationship.

All the best. Keep us posted.

ok that makes sense, now it hasnt made a noise at start up since the first time i posted the problem.
it did made the sound when slowly reversing too now, so i guess i can add that situation to the list lol

but thanks for the info!

so a bit of an update and question about this knocking problem.

i made an appointment to drop my car off at ford this week. so we’ll see what it turns out to be. and ford doesnt give a rental car unless you bought the car at their location.

question is that some friends are suggesting that it could be ball joints or the wheel bearing. any input on these ideas?

thanks!

[suleman09]

really? i never knew that. Thanks for letting me know!
i think im going to Ford come monday lol

[suleman09]

Oh i’m def not trying to fix it myself, i’m just trying to figure it out lol

And the only reason I havent taken it to Ford yet is because this is my daily driver and i have no other car to drive and i work 6 days a week. so its very hard for me to get it to Ford and leave it there for more than a couple hours. I’m just so busy with college and a full-time job you know. I’m trying to find time though

Quoted From BigC:

Hi suleman09,

A quick inspection of the engine oil would be good. Is the oil level at the proper level on the dipstick? Also, what type (weight) of engine oil does the ’10 Mustang call for? And, what type (weight) of oil is currently in the vehicle? Just wondering if the engine is not getting proper oil pressure. The fact that you hear the loud knocking noise on start up (in park) would lead me to believe it has to do with moving parts (engine/transmission related).

Hey BigC,

Just to let you know what’s going on with the engine. I just changed the oil not even 1k miles ago. and it calls for 5W30 Synthetic and that’s exactly what i put in it. I always work with what Ford recommends you put in it.
And if it were an internal problem with the moving parts wouldn’t it knock while running as well? or is that just an assumption people make?

Quoted From BigC:

Thanks for the update suleman09. Glad to hear about the oil. My initial thought was that low oil pressure might be causing the loud knocking noise in the engine compartment, or a partially plugged passageway in the engine compartment, that under low oil pressure, does not get proper lubrication. As you stated, you are using the proper oil for the engine, so it is probably not that. The car would probably exhibit more of the knocking noise more often.

Definitely curious to know what the problem (and fix) is. Keep us posted.

No problem, i’ll def keep you guys posted.

By the way, my buddy suggested something that sounds interesting. He said maybe it’s a CV joint going bad or drying up?
That sounds like a pretty good guess but that makes me wonder about the knock at start up, it’s only done it once in this week so im not sure.
Any input about a CV problem maybe?

Quoted From KLFER:

Are you sure it takes 5w-30 full synthetic. last i knew it was 5w-20 synthetic blend? also that car does not have cv axles. it is rear wheel drive with a solid rear axle, but they do us cv joints on the 2 piece drive line with a carrier bearing. might want to give that a look over. but you did say the noise was from up front. i would jack the car up shake the tire side to side and up and down to check for something loose. i would pull the tire off and check the brakes make sure the caliper is tight along with the bracket and make sure the pads are tight in the caliper, since it made the noise while braking. i would check the strut also since it made the noise while turning might have a bad strut mount. i would also check the sway bar the bushings and end links. hope you get it figured out. if the starter bolts were loose i doubt it would engage the flywheel properly, but you never know. transmission mount seems unlikely but might as well check it out. good luck man.

Im pretty sure it does but in my own opinion i dont think the oil has anything to do with it because ive been putting 5-30 fully synthetic in it since i got it and its never made the problem before, but then again it doesnt mean it couldnt just start happening.

but yea i’ll def give those a look over, thanks a lot for that input.
if i can’t get it figured, Ford can have fun with it 🙂 lol
