The back of the car goes light over a mid-corner bump, then settles a beat later than you asked it to. Not a fault. Not something an alignment will fix.
It's a rubber bush. The factory rear trailing arm bushing deflects under load — 034's words, not ours: the rear end feels "vague and loose", the geometry moves while you're leaning on it, and the car pushes wider than you aimed. Most obvious exactly where you notice it, cornering on an uneven surface, where the back can feel floaty. Volkswagen and Audi used the same rubber bush from a base Golf to an RS3.
034 replaces the bush with an Aurora spherical bearing — a motorsport bearing on a self-lubricating Teflon race, held in a billet aluminium housing on stainless spacers. Where rubber deflects and polyurethane binds, the bearing lets the suspension move through its full travel with nothing lost in between. The geometry you set is the geometry the car keeps, at the moment it matters.
It arrives as a complete arm — new factory steel trailing arms with the bearings already pressed in — so it bolts straight on, and it's rebuildable rather than replaceable when the day comes.
The honest part: 034 rate this Low to Medium on noise, and they're specific about why — expect a little more rear brake noise at low speed, more so on aftermarket pads. If you want a silent car, this isn't your part. If you want to feel exactly what the rear axle is doing, it is.
Fits Mk7 Golf, GTI and Golf R, Mk8 Golf R, 8V Audi A3 and S3, RS3 in 8V, 8V.5 and 8Y, 8S TT, TTS and TTRS, plus Q2 and RSQ3. Golf R years are the fiddly one on 034's table — send us your chassis and year before you order and we'll check it properly.
034 recommend an alignment after this job. So do we — it goes on our rack afterwards and leaves with the printout in your hand. Changing what the rear axle does and not measuring it is half a job.
