For the 3rd year running I have had an advisory on the MOT about oil misting on the front shocks, I know this is quite common but my car has now covered 162000 miles on the original shocks! I have not noticed much change in handling of the car but have just ordered new shocks for the front & rear Bilstein B4s. My question is do I change the top mount as well? not noticed any knocking or other problems.

Congratulations on getting your money's worth out of the originals! Also, credit to you for buying some really decent replacements, they will serve you well, and you'll find the difference very noticeable once they're fitted!

 

To answer your question, I would say yes, at that mileage it's worth replacing the top mounts at the very least. I'd be getting the mechanic to check the other joints too whilst he was there - lower arm bushes, anti-rollbar bushes etc. I bet they're all looking a bit tired!

 

 

Yes worth changing the front top mount and bearings as at 162k as it will save you future labour costs.

Misting shocks is a funny one - As with you one car I had had misting shocks noted a few years in a row, but on another it was misting at MOT and 6 months (10K later the shock was  knackered).

 

Yes I'd do the top mounts
