I have an 87 Ram D250, 5.9L V8 truck, it's my fixer upper project to
learn more about cars. I just fixed a flat on the front passenger
side. Since then, whenever I go over 35mph and apply the breaks to
down/stop, the car vibrates violently(and I'm not using that term
lightly). It feels like the whole truck is going to fall apart.
Any ideas or help? Greatly appreciate it.
What I have done so far: I made sure all the lug nuts are tight and
secure; made sure the tire is seated right; the tire is the right size
My guesses: with some of these older trucks, you have to install the
tire at very specific way (i.e. if you took the tire off with the valve
stem at 6 O'clock, you have to put it back that way).
Second guess, perhaps the rotors are warped and I need to re-surface
How did you tighten the bolts? If you went in a circular fashion rather
than a star pattern you could easily have warped your rotor. Take it
back off and retighten evenly in a star pattern.
If the tires were balanced while on the vehicle then its possible it
would have to be put back on the same way. That is a very rare
situation and implies the rotor to be out of balance. Doesn't sound
like this is your issue.
I had a similar problem with a broken tire sidewall. (rolled on a brick at
If you roll on a flat tire or with wrong tire pressure you may broke or
damage the sidewall.
Try to replace the passenger side wheel with your spare or move it on an
It's easy to find out if your rotor is warped. Remove the tire and place a
straight edge at various places around the disk. Any warping sufficient to
cause what you describe should be easily visible as a gap between the rotor
and the straight edge - either in the middle of the disk or the inner or
To start with, you'll most likely get 15 people yelling, "Warped Brake
That may be true, but I kind of doubt it. You would feel that severe a
at all speeds, not just above 35mph. To make the whole truck shake like that,
would have to be a pretty severe problem.
Anything on the steering or suspension that's loose, particularly in the
end, will cause these symptoms. Worn out tie rod ends, ball joints, a-arm
etc. With a 19 year old truck, it could be almost anything. Get the front end
the air and check all theses things. Be sure and check the steering shafts.
Don't forget to check the back end, too. Broken shock mount, worn out
bushing, bad axle bearing, etc.
On 2004 Durango's there was a TSB issued for severe vibration when
braking at speeds over 65mph. This happened with mine. No notice of
any problem at lower speeds. The problem was with the rotors. Probably
a combination of the warpage and the design of the calipers. Above
65mph the calipers began chattering horribly. It can happen.
Since it happened right after changing a tire my bet is still that the
rotor became warped from improper torquing of lug nuts.
Not true. My wifes Cheeroke had warped rotors but it was far worse
are higher speeds because the warp more as they heat up from braking
forces. Hers did no shake a lot until the rotors heated up. It is
possible for a rotor to be fairly flat when cold and warp big time as
it heats up.
Define...."fixed a flat"
Did it have....ANY...brake vibration before the flat?
What part of the truck did you jack up on to raise the truck up?
(keeping in mind it's a 1987 fixer-upper)
The controll arm bushings fubarred when the truck was lifted up.
The Ball joint came loose in the controll arm when the truck was lifted
The tie rod "ball and socket" popped when the truck was worked on.
You took something off.....that you did'nt put back on.
You put something on....that you didn't take off.
(changed the wheel to a different one...a smaller one)
You're lieing.....and you did more than jest fix a flat.
there are other possibilities...
from my experience...those are the most likely.
(not necessarily in that order though}
(experience has made me start at the bottom of the list..and go up)
do a repost...
let us know.
OK...The tire was flat, I took it off the truck, put green slime in it,
inflated it (all I had was portable air compressor that attaches to the
cig lighter and of course the cig lighter in the truck doesn't work.
So, I had to take the tire off of it and inflate it using the cig
lighter in my other car). Put it back on the truck. tightened lugs in
star formation. But did not use torque wrench.
Is that detail enough?
I put the tire on. I drove it for about 5 miles to spread the green
slime. Few days later, this problem started.
This is where I think I went wrong after readying your email. I jacked
the truck up from the frame area to the left of the tire. Since the
tire was flat, the hight I lifted was enough. When the tire was
inflated, the hight the jack lifted wasn't enough to fit the tire back
on. So I left the car up at that hight on a stand. Then I put the
jack under the control arm and raised it enough to where the tire fit.
Nothing else came off, just 5 lugs and the tire.
I put back only the tire and the lugs
Lieing is such a harsh word. I just didn't include all this detail the
first time because it never dawned on me that it might be important.
Here's some of what I'ma thunk'n...........
The flat tire deal is just a coincedence. Now you have a completely
unrelated deal going on that just happened to occur after you fixed
the tire and you need to inspect the frontend and brakes.
That's where the prob is.
When you lifted the truck under the controll arm, an already failing
part fubared. Now you need to inspect the front end and brakes.
Also, could be a steering linkage part.
You are slowly learning the benefits of posting...........
ALL the Facts surrounding your symptom in order to get speedier and
more acurate "guess's" as to your problem.
If that "scissor" jack slipped and you heard a gawd-awfull clunk when
it happened.....suspect something gave.
In any case.....
check the controll arm parts, steering linkage, brakes, and wheel
on that side.
