pop sound from front end.

[MustangChris]

Hey all... another one of those kick @$$ "my car makes a funny sound" threads...

when I come to a FULL stop (and your cars weight shifts back) i hear and feel a "pop." I beleive its from the front end because I feel it in my floor board and petal, not my butt of my seat.

also, it occationally happens when going over a bump.

it only happens 25% of the time (if that.) it took me about 10 tries to show one of my friends tonight.

the thing is... i replaced EVERYTHING on the front end of the car... so i have NO idea what could be making the sound.

new cobra conrtol arms (FRPP)
new sway bar end links
bbk gripp springs
tokico (used) shocks
MM CC plates
MM bump stop kit
99 cobra steering rack (used)
MM aluminum rack bushings
brand new drilled rotors (stock size)
brand new brake pads (OEM replacement)
brand new brake dust shields
new bushings all around
MM solid motor mounts
MM solid steering shaft
brand new yokohoma 520 tires

Please note: my bump stop kits were loose on teh steering rack, so i tightened those.

i mean, the only stuff stock left on the front is the k-member, the sway bar, and the steering spindles... and i doubt they are the problems... well, maybe a wheel bearing? whats left? it just started this the other day...i think ill check the caliper bolts to make sure they are still tight. other than that, im out of guesses. i checked a few things today, but i dono what else to do than to make sure some nuts are tight and to tug on a few things and to turn the wheels. lol.

Usualy when I hear a pop like that I think shocks/struts. Since yours are used, It might be a good place to start. Jack up the car and check the shock/strut bushings, and sway bar links and bushings.

 

[MustangChris]

bushings on the shocks? .. ? loll huh? they bolt to the CC plate and then the spindle. i dono where the bushing is? i put a brand new bump-stop on it when we did the front end.


but thanks for the help, ill take another look today.

 

[Scarface]

you dont have strut bushings since you have MM CC plates. i have a similar pop, havent tracked it down yet either.

 

[MustangChris]

well hurry up and track it down. so i can fix mine. lol.

 

[MustangChris]

my friend mentioned ball joints..... mine have roughly 3,000 miles on the cobra control arms... >.< i even TQed them to spec (didnt even max out the spec either. right in the middle!) boo.


any ideas?

I am having the same problem. So far the only thing I have not replaced are the shocks or wheel bearings, but the wheel bearings check out ok (no wheel play), so I assume that it has to be the shock absorber. Externally everything checks out, so maybe it is something internal???. By the way the shocks are KYB AGX's
Post your solution when you find it.

I am sitting here holding my Tokico shocks, and there is a bushing at the top where it mounts at the shock tower.

weeeellll i was going to look at pics of shocks off stang suspension, but they seem to have shut down... do you have pictures by chance? all i remember there being was the dust-cover with the rubber top on it. as for the shock, it just had a metal post. but as i said, im going off memory...

There might be some pics here http://public.fotki.com/marywillowmoon/matts_stuff/project-car/ if you want to browse through all 18 pages. But I don't think so.

 

[MustangChris]

these are kinda what mine look like. the top "shaft" part of the front shocks on my tokicos were the OEM ford-style ones.... just plastic housing with rubber on the top. i replaced them with an aftermarket kind with a taller bump-stop.

is that what youre talking about?

 

[uncltrvlnmatt]

Not at all.

This is the best I could find. Mine look nothing like yours. They must have made a change for the modulars.

yea, thats what mine look like. sorta. lol. except for minor changes which i would expect from brand to brand...

what part of that shock should i inspect?

 

[95gtdrop]

Make sure your trans mount is tight. Mine was loose and it made popping sounds also

if you are refering to the front strut bushing, the MM CC plates replace that rubber bushing with a bearing.

There you go, no need to check something you don't have.

 

[tommybunz]

check your control arm bushings, and believe it or not brake caliper bolts

check your control arm bushings, and believe it or not brake caliper bolts
