Yup, not when braking, only at highway speeds. I changed front tire pressure tonight on my way home from work to 40lbs and it actually rode better. Hardly any shaking, but it was still slightly noticeable.

I would think that if it was the tires there has to be something wrong to make them do that???

This is a problem that Ford has known about for years, and there is a TSB out for it. At 50-60, the front control arm bushings cause the shake. Since you eliminated everything else, this is what it is. Mine used to do it too. Solution: Put on some 03 Cobra front control arms that come with new ball joints, better bushings and revised geometry for ~$190. Much cheaper than paying for new bushings and ball joints and the labor. www.buyfordmotorsport.com and www.mcford.com has them, part number M-3075-D , however they don't list a price anymore. I got mine from mcford for about $205 shipped 6 weeks ago. Along with the SFI Powerbond balancer, It was a night and day difference. Felt like the car was gliding on the road. My old bushings were rotten and cracked (142k)

FYI, www.corral.net has the best tech forums on the web, hands down. Stangnet doesn't compare.

Hmm!I never had any problems with any of my fox bodies or up with tire shaking.I had ROUND tires and a good front end though also.:jeff:

Right, it's a SN95 problem.

Had an 01 Bullitt and now have an 03 Mach with ZERO tire shake.Like I said in previous posts on this thread majority of any tire shake WILL be caused by out-of-round tires.:jeff:

[texsn95]

Found out it's narrowed down to the 94 to early 96s with the "too soft" front bushings. Out of round tires will shake at any mph, not just from 50 to 65.

Give me the TSB you speak of.Out of round tires will not shake at any MPH either unless it has a tire seperation.A tire with excessive road force or with excessive runout will come in to the "shake" around 50 mph on up.Most tires with over .030 runout you will feel while driving.Anything with over 20 pounds of road force you will feel also.Granted any worn out suspension component can cause a shake but I personally have never seen any mustangs with failed control arm bushings.

We don't even know what year his car is. If it's a 96, it's probably the bushings. 97-98 and it might be the tires. I'll find the actual # for it though, as this was kind of hush hush, and people had to do alot of things and pay alot of money to track down the problem on those years.

Just wondering, where do you get all the technical numbers? 20 pounds of road force? It's just common sense, if something is out of round, it'll show up. A tire doesn't need a separation to vibrate. I've run over shit that has stuck to my tire, and I felt the vibration all the time. Now if it's an issue with the tread pattern itself, I can see where a certain speed could affect it differently.

And the bushings dont "fail". They're just too soft. You can look at mine if you want. That's why there are Ford "revised" A arms out there from the 96+ years available to the 94-95s.

I do this 5 days a week for a living.I know these numbers I spoke of from my years of expertise.I have equipment to check these things also.I have access to all TSB's Ford comes out with but really don't feel like referencing all the way back to 96.Only A arms I know Ford has revised are the ones that were on all 03's and it is for bushings being too soft and they create a noise also.How many thousandths would you consider a tire being out of round normal?How much on a rim?How much road force?I would say 95% of all vibration or steering shake on a Mustang will point to the tires.

Have you actually read the links I posted? My car did exactly the same thing as his for years. Numerous other people's do the EXACT SAME THING. The problem in almost all cases was not the tires, it was the bushings. Just because you don't know about it doesn't mean it's not a problem.

Edit: Found it, his car is a 96. It's your bushings dude. Get the 03 arms, you'll love em.

I could careless about the links you posted.Give me a TSB as you had said earlierDo you work on cars every day for a living?

I've been working on Mustangs for over 10 years, does that count? I've dealt with this problem myself and found the solution. Yeah, you could care less about reading how others have had the exact same problem? Whatever dude. It's not all about what YOU have worked on.

So working on Mustangs for 10 years qualifies you as being a technician?All I asked is for a simple TSB.Show me proof.Whatever is posted on the net is hersay IMO.Like I said "I" do this for a living.GIVE ME A TSB!I've been working on Mustangs since '86.Been doing it at the dealer level since '91.So are you trying to say if this is such a COMMON problem don't you think I would have run across this?I probably work on 1500 cars a year FYI.
