Got a quote to replace upper and lower track control arms and lower ball joints on my L322 for �615.

Both sides

Sounds like a good deal? Garage is reputable

How much is parts and how much in labour?

the arms are about �40 for OEM (or �150 for LR gen) for the uppers and �60 for the larger lower arms OEM. per side plus the ball joints which go on the larger arms, all in probably could be done with OEM parts for �115 - �120 in parts per side plus labour.

leaves about �375 in that for labour, depending on their hourly rate, sounds about 4 hours. possibly a little bit steep, I'm sure someone in the trade will be along to say how long it should take. There is nothing that can't be fixed with a hammer😜😜

I haven't got the quote sheet handy - I think labour worked out at around �200. I will check the quote sheet again when im home for full breakdown

I suppose you need to really ask if they're using genuine parts or just getting them from Eurocarparts, And is it just a general garage, main dealer or an independent specialist?

Its a place called Elite in Rainham. They are are wheel/tyre/suspension outfit.

I will find out if they are genuine/patent parts

Lemforder / Delphi parts are OEM and are OK.

personally would only go with genuine or OEM. I have taken original parts off to find them stamped with Lemforder Logos  There is nothing that can't be fixed with a hammer😜😜

Had this work often here in my garage, sometimes all around 2 hours, sometimes 5 hours, because of very difficult build out of the ball-Joints, very rusty! L405 SDV8 2017 + Lancia Flavia Coupe 1964 + RRS L494 3.0 SDV6 + C220CDI Convertible 2021
