I'm not sure how many aftermarket ones they have fitted. Do you fit the superpro differently to standard? Is there anything I should look for to spot if they have done anything wrong?

It's not uncommon for it to be done wrong, which will induce extra noise. Many people, especially with autos, reckon there's minimal extra NVH with comfort spec super pros.How often do you change your diff oil? When did you change it last? 1 Link to comment Share on other sites More sharing options...

You should not experience any nvh increase with properly installed COMFORT series bushes. 2 Link to comment Share on other sites More sharing options...

I installed the front bushes to the exact distance the previous ones. Link to comment Share on other sites More sharing options...

Do did already have high level hearing loss?Correct. And serious it's quite as.It's only the solid centre that transmits the noise. My original setup was genuine Ford sides with a solid centre and it hummed real bad. Swapped out the centre back to a genuine Ford and it was quite again After they died I went to the current setup of solid sides and comfort centre.
