Difference between new and old is amazing, the noise that the worn bush generated was unbelieveable, the car is now as quiet as it was the day I drove it off the forecourt 40k miles and 2 yrs and 23 months ago
To summerise:
Cost of part...£6.54
Time taken to replace...2 mins tops.
Tools needed... 10mm Ring-spanner.
Tea?...yes please (no sugar)
Biscuits?... a mint kit-kat will do nicely.
Downsides:
The Cost of part, £6.54 inc vat...ouch!
The fact the bush is sold only with the metal bracket which in my case didnt need replacing and I cant see it ever needing to be unless the fixing stud/nut rusts or strips its thread.
It appears the new part is identical to the old and made of similar material which means in theory it will wear out again in another 3 years.
