Hi all, My EF Fairmont had rear Ultra Low King Springs and fronts that matched the same height, only i dont know wat brand they are. Whilst they were in, I had this shocking vibration from the diff....and no-one seems to b able to tell me what it is...mechanics these days, slack bastards. Was wondering if anyone could tell me.....
Since im looking for superlows now, those springs are for sale if anyone wants to buy them....but im still curious as to why i had that vibration...

Thanks All

Most likely,
that the springs were so low they altered the pinion angle on the diff past what is acceptable. You new higher springs may fix this....but only to a certain level.
