Well, you may not realize it but....
You have just saved an absolute fortune on:
Front exhaust eventually snapping or the flexible joint blowing through excessive rocking of the engine block.
Drive shafts, inner CV joints and their respective cups wearing unevenly.
Oil leaks from the diff housing seals
Gear linkage selection issues.
Breaking or loosening of earth straps
Wearing through and splits of turbo hoses
Unnecessary replacement of Upper wishbones, lower wishbones , Drop links and anti-roll bar bushes trying to chase down mysterious knocks...
Good work, finally someone who uses some common sense and logically works through issues
Always remember... There is always, always a cause to a problem and a consequence that follows with mechanical parts and ancillaries... Sort the Root issue and it works out cheaper in the long run... That's exactly what you did with the engine mount
Top work and when you look at it, three hours of hassle seems worth it when you look at the list of potential issues it would eventually give
