Front upper suspension arms , d3 s8
 

Would anyone have the correct code for the front driver's side front upper control arm ,the rubber is damaged on the track rod and and I'm going to replace it as part of the winter maintenance,i've checked through posts and parts diagrams on net and the different versions and codes appear to be a mine field ,I contacted ecp as they have lemforder and trw listed but chap I know in there says although it's listed for s8 it's actual for the a8 and they don't do the ones for the s8 ,or if you had the correct lemfordor or trw part no and were to purchase that would be even better .
Thanks

Are we talking about 13 and 14?

Part numbers are dependent on VIN number with the S8. Details of both sets of top arms (left and right) are as follows:

VIN up to 4E-4-012 700*
Left front upper - 4E0407505E
Left rear upper - 4E0407509E
Right front upper - 4E0407506E *
Right rear upper - 4E0407510E

VIN past 4E-4-012 701*
Left front upper - 4E0407505F
Left rear upper - 4E0407509F
Right front upper - 4E0407506F *
Right rear upper - 4E0407510F

NOTE: The one marked with '*' is the one you specifically asked about, but just provided a list of both sets.

m&l in omagh have meyle ones they would be the oem equivalent just done mine today.

Try and loosen the pinch bolt sometimes they are a nightmare to get off.

Thanks chaps ,it's no 14 i need to change ,I was only going to replace it as rubber is damaged on the track rod end ,i'm assuming I don't need to change both at the same time ?

Good point, and having gone through the process of removing a seized one, something I prefer to try and forget!

If required, part number for the bolt is N10576802 (M10x105x26) and costs about £4. The part number for the nut is N10272302 and costs about £2. If you plan on keeping the car, just replace them anyway.

Shouldn't it be number 13 as 14 is the upper 'rear' arm?

Thanks Sean you are correct ,I didn't spot that that was the passenger side diagram

I had a go at that this evening (as well as the crankshaft seal etc and ps pipe replacement) i got the bolt out fairly easily even though it was seized solid , I purposely rung the head of the bolt and sprayed penetration oil in to hole and cleaned the 2 slits in the strut and sprayed them as well , removed the nut and added 3 washers refitted nut and kept tightening nut with a spanner and slacking and increased washer space by sliding in open end spanners as required to pack space between nut and strut and continued to tighten nut and it pulled the bolt out ,I had to cut end of bolt as it was hitting strut before it was out but it was well freed as that stage so a roll pin punch and hammer tapped out remains ,I looked at removing arm from strut and gave it a gentle tap and lever at the same time but it didn't seem keen on moving,is there a trick to lift it without damaging strut ?

is it the pinch bolt at the ball joint end or the bolt at the top of the arm at the upper part of the strut Keith?
