P38A wheel wobble

Hi all yesterday i had my wheels swapped around, front to the back and the back to the front, everything seemed ok but if i went over 50 mph and had to brake there is a terrible wobble on the front , would the front wheels not being balanced cause this as when i had them put on , not long ago, they were balanced , iam thinking i will have to get them re balanced but i was just wondering if anyone else has had the same problem .

If the backs were originally not ballanced and they are now on the front there's your answer

You'll have checked the wheels are tight I'm sure?
Could be an imbalance caused by crud on mating faces between wheel and hub, maybe a balance weight was knocked off, maybe you hit a pot-hole and you now have a damaged tyre......so many possibilities.

If you paid someone to swap them then go back to them.

Are they the original one's if l322 wheels are the spigot rings fitted.

Also the book tyre pressure is different front to rear.


You may be running 38psi on the front now
