Front Suspension

NB. If working on Syncro front suspension and replacing parts it pays to have access to the ETKA Parts program, through your VAG parts dealer’s good offices of course.

There are two different track-control arm (lower wishbone)/ radius rod/stabiliser link bar (anti-roll) setups on syncros it seems; the major difference being the lower track control arm design, the earlier type having a more complex forged radius rod incorporating the stab link bar fitting hole, this being bolted to the tca/ball joint via 3 bolts and uses a heavy intermediate plate through which the lower ball joint taper fits.

The later arrangement has a simple radius rod threaded at each end, which screws into the tca, this being a more complex piece, but not requiring the additional plate and bolts.

The former has the possible advantage that the lower joint can be removed with three bolts rather than splitting the joint taper. Together with this, the stab bar drop links are different (handed on the later versions)and possibly the lower shock absorber mount details.

This change came about circa Chassis No. F 24-K-048 497 (October 1988)

Some earlier radius rod and attachment detail changes seem to have taken place after F 24-G-175-000 (July 1986)

Stabiliser Link Bar (Vert Link bar, threaded M10 at bottom with eye-end @ top) For 21mm anti-roll bar

Earlier 251 411 049 F (which still has to be installed handed, seemingly having a slight bend near the bottom, bends inwards at the bottom)

Later 251 411 049 (J left; K right)

Not same as 251 411 051 (Early 2WD Cranked) or 251 051A (Late 2WD Straight) AFAIK, but ETKA gives two part nos.(AFAIK)

Don’t try undoing the 10mm nut at the bottom of this unless you have to, they break the thread off, the sleeve probably holds moisture and ends up as part of the thread – when refitting a repaired, new or original assembly, use plenty of assembly compound to prevent corrosion, anything is better than nothing e.g. copperslip, or grease on threads and inside of sleeve. They can be repaired by cutting off at the shoulder/ redrilling and threading carefully with 10mm or equiv metric studding – or gas welding. Use the spacer sleeve (251 411 047) as a guide!

The stab bar link also requires (num per side):

Lubes for Transaxle and Front Diff.

Do not use GL-5 spec. diff oils in the Transaxle/Gearbox unit, but they can be used for the Front diff.

Use any good GL-4 spec for the transaxle:- VW quote 80W/90 GL-4

If you can afford it, one of the best (for protection and gearchange quality) is Redline MT90

(Redline MTL 75W80 (GL-4) is a bit lighter, vcan be used but MT90 is the one)

They also do a GL-5 (front diff) Redline 75W90

Capacities (Bentley): Transaxle unit – 4.205 US Quarts (approx. 4 litres); Front diff – 1.605 US Quarts (approx. 1.5 litres)

(Some say Transaxle is 4.5 litres, there is a portion under the diff, held back by a ball-valve, that doesn’t drain)
