I have a 1997 Freightliner classic XL. Had brakes and drums put all around last week. Left home Tuesday and was going down the road and started to slow down to exit and all at once my front wheels felt like they were wobbleing. shook the steering wheel really bad. Scared the crap out of me. Stopped and checked for loose lugs on the front, nothing found.It never did this before I had the new brakes and drums put on.It doesn't do this wobble all the time. any ideas? Thanks <img src="http://Truck.Net.infopop.cc/infopop/emoticons/icon_confused.gif" alt="Confused" width="15" height="22"><!--graemlin::confused:-->
as simple as a bad tire (slipped belt), tires not balanced properly, a bent rim, or it could possibly be a bad bearing, or an out or round brake drum.
I would start with the tires and go from there. Carefully exmine the tires to see if by some chance they are cupped or if the belts seem to no longer run smoothly around the tire. If the tires look and feel fine to you when you run your hand around them take them to a good tire shop and get them checked there. (some times spinning the tires by hand will reveal a slipped belt as the tread will wave back and forth).
You didn't really say if this occurs only when you hit the brakes or if it occurs when your speed drops below a certain level.
I will always be a mutter trucker at heart.
If the drums are balanced, a balance weight could have fallen off a steer axle drum. Look for a spot where there is no paint on the drum. I doubt you could have burnt the paint off the new drums yet.
Too little knowledge is a dangerous thing. JLK
Take a look at the list on the Pete steering
trouble for a base check on the front end.
The drag link not level is not the problem.
The thing that draws attention is the drums and
wheels were mounted - I just had a tirebuster
try to bolt a wheel on my truck by going around
in a circle instead of crossing the lugs and
starting the first one lightly so the wheel
can center it self on the cone seats.
If it is a hub piolit this won't have much effect.
Loose king pins and bad shocks are the most common
causes for the wobble that is set off by an out
our of balance wheel drum assy. It generally
takes 5-6 oz out to start a harmonic wobble.
Just R&R a steer tire can make that much
difference. I paint a stud to mark the valve
stem so the balance goes back where it was.
Are we far enough out of Dodge yet?
