big speed bumps are satans weapons against mustangs

[will_95gt]

and your sure its coming from the rear of the car? as far as your quad shocks: there should be two shocks on each side of the car. one going up and down, the other going front/back.

to check your calipers you will need to take off your wheels.

when you jacked up the car to check out stuff, were you jacking up the rear? i would try jacking up the rear and then putting stands under the frame rails and letting the rear hang. this will better simulate a hard braking situation. then just start shaking stuff to see if anything is loose.

ok, i took off my rear pass side wheel and poked around... still have no CLUE what i'm looking for lol... nothing seemed loose. I doubt u can tell much from the pictures but i figured i'd let you guys get some idea of what i'm looking at...

the second and third pictures show something i thought was kind of fishy. My pass side rear tire was jacked up all the way and i removed the wheel so the car was at a strange angle but still the muffler shouldn't be touching the drive shaft like that right? I figured this could be the source of the banging but i have no clue... anyways i hope these pictures help out a little.

in no way shape or form should your muffler be hitting the driveshaft that is whats making the noise probaly due to the groove in it

 

[will_95gt]

well when the car isn't jacked up like that the muffler isn't hitting it...it is kinda close though... anyways, maybe if i stick a cloth inbetween the muffler and drive shaft and then drive down the road and do a break check to see if the noise still occurs....

if anyone knows any reason why i shouldn't do this test or knows an easier way to see if thats where the sound comes from please tell me.

The cloth might rip off, dunno if that's a good idea. You should check the exhaust hangers and the rubber isolaters they're hanging on. You should be able to loosen the bolts holding the catback on that side, and shift the muffler out of the way some.

Also, I saw your spring isolater in the first pic is cut. That mgiht be causing some noise as well. Somethig to put on the upgrade list.

 

[fawcett]

looks like that muffler is too close-i hate to sound like a dick but thats a problem. your exhaust moves when you get on 'it and when you hit bumps. its held on by rubber hangers which allow it to move. if you cant do fix this yourself get it to an exhaust shop and tell them to check your muffler/driveshaft clearanc issue-they can take it from there.

im guessing you moved your exhaust alignment on impact. its just metal it can and will bend-luckily it can be bent back

Drive Shaft for the win! I deserve another cookie.

 

[will_95gt]

gcom, lol looks like u got it... +10 for u

You should be able to loosen the bolts holding the catback on that side, and shift the muffler out of the way some.

Do u mean i could loosen the bolts holding that catback to the midpipes? and then try to move it over a little? i'm not sure if those are the bolts ur talking about... but if i did that i'd have some exhaust leak from that connection right?

anyways thanks for the help so far guys, i really appreciate it

define: to dislodge, to replace by form of collision

(bump)

 

[will_95gt]

ok, mas pictoras

this time i put it on some jack stands and after further inspection it looks more like the h-pipe took more of a beating than the actual catbacks... and sence the h-pipe is bent or.... kind of dislodged, i figured that might be more the problem... anyways once again: pictures. I want y'all to see what i'm seeing.
<p>
ok heres a shot of the cats, they look uneven, but this is my first car so i'll let u guys tell me

this is the scar from... the horrible speed bump

<p>
ok, right under where the transmission meets the drive shaft the two rubber hangers that hold the h-pipe mounts are kind of uneven. One of the little rods that are supposed to go into the rubber hanger doesn't even meet the hanger...so its hanging on just one right there.

fwiw, when you brake the rear of your car rises up and can cause things to happen the don't normally happen...which is why it hits when u jack the rear......just tired and rambling.

good to hear you found it

CATASWAMPING!


looks like you found a way.

Please please please be absolutely sure about jack stand placement. Get under an improperly supported car and you are signing a DEATH WISH. Seriously. Also, buy some proper wheel chocks - stop using 2x4's. And always work on a LEVEL surface.

I believe the proper jack stand location is not where you have it, but at the same point you put the jack to raise the car. And that IS noted in your owner's manual.

On your problem, I agree with the other posters who say there is no way your muffler should be that close to your DS (jacked up or on the ground). The mark on your DS is key evidence of contact. It's hard to tell from pictures, but your mid pipe may be bent out of whack. If so, I don't know whether it will be more work to fix it, or just get a new one.

But if I were you, I'd start by loosening all the bolts at the header to mid-pipe, and mid-pipe to cat-back. Then try to wrestle the exhaust back into proper position. Start from the front of the car and work back. Get that mid-pipe back on both hangers. And get the passenger muffler away from the DS - about the same distance and the driver side is in your picture.

Oh, the other way to tackle this is to find a good muffler shop and have them do it. After about $50 at a reputable shop, and you should be good to go.

Good luck.

 

[will_95gt]

yeah thats what i figured. I actually did put those stands from the point i raised the car. I was going to raise it fromt the differential but my neighbor said he wasn't sure if u can do that on mustangs or not... he said hes seen some axles "get the banana effect" from doing that

as far as the lip that runs the length of the body that ur supposed to jack it up from when using a tire jack... that thing is piss poor and very warped/bent from previous owners jacking it up from there

anyone here still have their users manual want to check for me on the correct jack stand placement? thanks guys.

btw i saw a picture online of a guy who drove his car onto four ramps that it looked like he made himself out of wood... anyone recomend this? If you havn't been able to tell by the threads i post, i absolutely hate paying ppl to do things/buying thigns that you can do/make yourself... even if it costs the same as buying it.

btw... stangnet, i love u
:SNSign:

A safe place to place your jack stands is on the front LCAs. Place the center of the jacks between the 2 openings, just under the spring perch. Once on the jacks push on both front fenders to make sure there is no movement. Where you have them now is a recipe for disaster because you will be pushing and tugging.

Also, I've done some research in the past and other peeps had scraping on the DS but it came from the emergency brake bracket just above the DS. Just something to think about. As mention before, loosen the exhaust and move the muffler over some. There should be no exhaust leaks because the male and female ends are like ball sockets and should seal, even at not so perfect angles.

To keep my exhaust from hitting the frame, such as in the rear, I've used electrial wire - solid not stranded wire. Pull, or have a helper pull/push the exhaust for clearance while you wrap the exhaust.

Next time go over that mountain slowwwwwly.

I don't. I'm sure if you made them strong enough you'd be OK. But how would you ever really know they are strong enough?

Better yet, pick up 2 sets of those plastic ramps that you can get at the parts store. Then you could jack it up and support the car on jack stands AND ramps. That should be the safest way to go. That's how I do it if I have any significant projects. And when I need the car higher up than the ramps will take it, I put a row of cement pavers under the ramps (or two rows piled ontop of eachother).

I like doing stuff myself too. Did my own gears, HCI, etc. But exhaust is one of those things that is just SOOOO much more efficient to do in a shop with a proper lift, that you might just want to think about it.

 

[will_95gt]

hm, ok. Good feeback for sure. Yeah took it off those jacks before i touched anything... i have ramps but the car is too low so i had to remove the front bumper just so i can drive up the ramps lol. whatever works i guess. I'd rather do a little extra work and be safe than having a 2 ton vehicle smash my face ;-)

front LCAs. Place the center of the jacks between the 2 openings, just under the spring perch.

do u think u can get me a picture of what ur talking about? i'd superly greatly appreciate it.

 

[Methodical]

Here is a picture. When I was under there I realized it may not get up high enough for you since you are doing the exhaust. It should work but if not it's good for future jackings.

 

[will_95gt]

thanks alot man, really appreciate it.

 

[MysteryMachine]

I jack and put my jack stands on the flat spot at the ends of the unibody

and beings nobody told you the little shock in this pic that runs diagonal is the quad shock

Also like mentioned before go over speed bumps at an angle and SLOW
