What is the replacement method for the Jetta rear axle rubber bushing?
4 Answers
Jetta rear axle rubber bushing replacement method is: lift the car, remove the two rear axle screws and oil pipe, then use the Jetta rear axle rubber bushing special tool to pull it out. Taking the 2010 Jetta as an example, its body dimensions are: length 4415mm, width 1674mm, height 1415mm, wheelbase 2471mm, trunk capacity 660l, curb weight 1091kg. The 2010 Jetta front suspension is MacPherson independent suspension, rear suspension is twist-beam non-independent suspension, equipped with a 1.6L naturally aspirated engine, maximum horsepower 95ps, maximum power 70kw, maximum torque 140nm, matched with a 5-speed manual transmission.
I once replaced the rear axle bushings on my Jetta by myself. It was a bit challenging but saved me some money. First, securely lift the car, then remove the rear wheels and the rear axle mounting bolts – a special tool is needed here to provide support. The old bushings might be rusted in place, so use a pry bar with lubricant to slowly work them out, avoiding any forceful hammering that could damage the control arms. Apply plenty of lubricant to the new bushings, align them properly, and ideally use a press to slowly push them in; doing it manually can cause misalignment. Be extra cautious throughout the process to prevent the rear axle from suddenly dropping – having a friend assist in supporting it is helpful. After installation, remember to get a wheel alignment, as improperly installed rubber components can cause severe misalignment. If you're doing it yourself, set aside a full half-day over the weekend.
The key to replacing rear axle bushings lies in the tools and technique. When removing the old part, I used a heat gun to heat the outer area of the bushing for two minutes—softened rubber is easier to press out. Before installing the new bushing, apply anti-rust agent to the metal contact surfaces, and slowly tighten with a C-clamp for safer operation than using a hammer. During installation, ensure the dust lip of the bushing isn't installed backward; incorrect orientation can lead to cracking within months. Don't rush to reinstall the wheels afterward—first, manually shake the rear axle to check for abnormal noises. Any friction sound between rubber and metal indicates improper seating. This precision work costs around 500 yuan at a repair shop including parts and labor, but DIY can save 200 yuan if you have the right equipment.
I recommend inexperienced car owners to go directly to a repair shop for replacement. The rear axle is in a tricky position, and working under the car really tests your back strength. Repair shops have specialized tools for disassembly and installation, which are faster and don’t damage the parts. If you do it yourself, you might get stuck at the step of removing the old bushing—I spent an hour slowly squeezing it out using bolts and nuts, while a repair shop’s hydraulic press can get it done in ten seconds. Remember to ask the mechanic to check if the rear axle control arm is deformed. Older Jettas that have gone over many potholes often have bent control arms, and just replacing the bushing won’t solve the problem effectively. It’s also best to have them adjust the four-wheel alignment data, as incorrect rear wheel toe angles can cause uneven tire wear, which ends up costing more in the long run.
