I know I harp on about this a bit
..
But I can only go by experience and i've bought a lot of parts from Ahem certain "Specialist" Suppliers ..
And Still got a pile of C*** ... the last lot fitted to my CDTi in 2014, a front arm , a wheel bearing ,a Rear bush and a rack , only the rack is still here , the rest failed with in 2 years.
And since then 2 arms , a Rear bush and one Bearing ? all Supposed top makes ..
so even relying on a "Specialist" won't save you .
Currently got 2 DMGRS arms/bushes waiting to go on, and you don't wanna hear what I think about that so far ?
