Saph cossie 4x4

Ive got a shake between 80-95 and when cornering left over about 60. At first i thought it was a unbalanced wheel or a buldge in the tyre so took the wheel off to have it rebalanced and its all fine.

The issue wasnt there before i took the car off the road about a month ago to do the sump seal. the only things that were touched would be the crossmember and engine mounts. Could it be something to do with them ?

Cheers
