Long Trip
« on: 17 August 2006, 12:17:46 »
Hiya People

Well I just returned back to the south after going back to my home town of Middlesbrough.

Its a 500 mile round trip so i wanted to check some things out when driving.

On the way home to the north after about 10 mins or so i was getting a vibration through the car very anoying but it seam to only happen at about 80 MPH once 80 was broken it did the same vibration at most speeds.

On the way back down south I decided to try and not break the 80 MPH limit and crused at 70 to 75 most of the way and it was smooth all the way so much nicer to drive i had acouple of points with the vibration but they passed and vanished.

Driving at 70 MPH all the way back gave me great MPG by the computer an avarge of 44 MPG
But I was on LPG all the way back so i am guessing i was not getting 88 MPG but more like 70 odd as i know you get less MPG on LPG than Petrol but looking at the price of LPG to petrol was 40.9 For LPG and 99.9 for Petrol.

So all in all i am happy apart from the slight vibration for time to time was wondering if the Front discs are warped which i think they are cud cause vibration

Probably a buckle in one of the wheels or else they just need balanced

Probably a slightly out of balance wheel. To confirm this swap the front pair over with the rears and see if the problem moves or disappears.

Agreed, I would go for balance first. Use a good balancing place, as Omega does seem to be fussy wrt balancing...

Propshaft problems can also cause this sort of vibration, but less likely...

Wheel balancing I would say.

Its not Omega wheels being hard to balance, it seems to be more to do with how the balancing machines are used and if they are any good. Some simply take a central reading and try to balance it out with two or even one weight. Reality is on wide(ish) wheels you need a balance reading at two speeds and on both edges and correct it with two weights.

Its short cuts by the fitters mainly.

Additionally, it seems, some fitters don't use small enough weights (or the machines aren't good enough)...

If you do go for the wheel balancing.....its worth making sure they take all the old weights off first!

Seems logical thing to do.....but i had my fronts rebalanced due to steering wheel wobble at 50mph.
It improved but not entirely gone.
So I took it back a few weeks later and asked them to have another go....different fitter this time...and he was shocked as one wheel had 90g of weights on it!
So it seems some fitters just keep adding weights to get it right and others remove them all and start again.

Been fine since  :)

STS, being a tyre fit company, can do balancing...

i am now on my second omega and both have had a wheel balance/vibration  problem at 80/90mph only i was wondering if this was perhaps a design fault as no amount of wheel balancing would/will cure it :-?

No - none of mine did that so check your front suspension components

If the vibration is though the steering wheel = front wheels

Vibration though your bum (the seat) = rear wheels
