vibration is this normal?

Ok guys this is the problem.At speeds over about 60 mph i start to get a vibration through the car where everything starts to rattle and am trying to find the source.I have transverse leaf front and rear with 2 solid axles.When i'm travelling down the freeway it can make my cd player stop playing.Now i thought it was wheel balance so i had this done and although it got slightly better i still have it.Is this normal with x plies and rigid axles? will i have to just live with it?................Marq

 

no , that's not normal , you have something out of balance or bent...like maybe the driveshaft,or a bad u-joint. .. could be a brake drum or brake rotor , even though you balanced the wheels/tires, they can be out of balance too

 

moree likely to be a brake drum i think.Is there any way around it ?

 

I had a buddy with that problem and it turned out to be his front wheel bearing nut weren't tight enough

 

Marc,put car on lift spin all tyres by hand and look for wooble ,out of round,ect. Have someone run car and hold crayon, chark to driveshaft should be a true line .

 

i had that problem for about a month then i dropped my drive shaft doing 80....

 

if it was drive shaft wouldnt it do it all the time instead of at a certain speed...............?....................Marq

 

no, I believe drive shafts will have a harmonic vibration only set off at certain RPM.

 

Anyone know the torque setting for front drum bearing nuts on 53 ford f100 drums.................Marq

 

This is how I do front wheel bearings...
about one pinkie finger's pressure on the spanner with the wheel spun by hand, then back the nut off to the last flat that allows the cotter pin to go in...

 

Yes they will. I have dealt with it many times.

What are your the u joint angles on your driveshaft like?
http://www.4xshaft.com/ This is geared to the 4x4 world, but the info is good and can be applied to any vehicle. I have seen some very low cars with the driveline going up to the rearend....angles are angles no matter which way. A driveline needs some angle, perfectly flat can create a vibe. make the axles at each end and the harmonics will cancel each out....If the pinion has 2 dergrees, set the ****** out put so it has 2 degrees as well.

 

Marq, I think you have to pst some more specifics if you want us to guess what the problem is.

Do you have a Ford tube style driveshaft? If so, I wouldn't consider it to be the culprit. Your bias plys are probably exacerbating the problem, wherever it's coming from.

I'd jack up each wheel. See if there's any play in each. Spin each wheel and see where it stops. If the same part of the tread is up (or down) when it stops each time, it's out of balance.

Marq, kick it up in neutral and see if it goes away.....

 

Ok guys i think i have it.I phoned my local drive shaft place and he said that he thought the uj bolts were too tight on the rear and to back them off and retighten to 14-18 nm which i have done and i can now listen to my stereo as the vibration seems mostly to have gone and i can now live with it at 80-100 mph .............Marq

 

yeah thats what mine was i changed my u joints the my dad "double checked" aka over tightened one side of the rear u joint and the vibration worked the other side loose....

 

the guy told me if you overtighten that one side of the joint is loose then the other is tight and it creates a tight loose effect which in turn comes out as vibration .At first it dont show itself cos the needle rollers are all ok but they then wear a slight notch and then the vibration appears.i'm hoping it will last for the time being and i hope i caught it in time lol......Marq

 

my dads roadster had the same problem with a brandnew set of wheels from wheel vintiqe.found out after 2 sets of tires,3balance jobs.found out the wheels were out of round,might be your problem.

 

Brake drums are balanced when new. You can have them balanced if you think it is the drums.

 

The front whhels are origianl but the rears are repop that may go some wat towards it.................but it's much better since i done the drive shaft...Marq

 

my anglia used to have this weird little slight vibration at about 70 or so.....i figured driveshaft.....changed it .....still had it ....slightly ......oh well ...the car fixed itself......hahah by the looks of the axle ...it had been cracked for a while..... brandon

 

The steering wheel is on the wrong side of the car.

 

Over here us hotrodders prefer lhd cars as is mine having a rhd hotrod just aint the real deal ,plus if we want to sell it the Europeans will have them or ship it back to the states like i know a few have gone back so that aint my problem my hotord is American through and through bar the battery lucas generator and regulator.................Marq

 

Drove lhd cars in UK for years. P***ing (overtaking?) is an experience to be remembered.

 

try doing it in a 35/36 pu with tiny rear screen tiny mirror and a useless peep mirror it can be hellish .I have to say though i just love driving American iron it gives me a real buzz just getting parts is a nightmare......................Marq

 

For some reason, this reminded me of something that happened to my wife in England. One day she told me she had gotten stopped for speeding and would have to go to court. After her court appearance, she told me she got fined 100 quid. Several years later she got a little tipsy and I heard her tell her sister she got fined 300 quid. Since she was kind of cornered, she told me the truth.

She had left the motorway, but was still on a dual carriageway (4 lane road). She p***ed an unmarked police car and the car they were chasing. The cops abandoned the chase on the other car and took off after my wife. She never told me her speed, but she was in an Audi 80 Sport 2l. It was capable of 125 MPH.
