The tool kit should include not only standard wrenches, but also specialized equipment. To dismantle the hub, you will need a powerful wrench, a 19 and 21 mm socket, as well as a special puller for pressing out the retaining ring and the bearing itself. If you don't have a puller, you can use a hydraulic press, but this will require removing the entire assembly.
Don't forget to prepare cleaning and protection products. Penetrating type lubrication WD-40 or an analogue will help to unscrew the stuck bolts securing the brake caliper and hub to the steering knuckle. A wire brush is also useful for cleaning the threads from rust and dirt before installing new parts.
- 🔧 Socket wrenches and sockets: set from 10 to 24 mm, including extension for levers.
- 🔨 Hammer and hammer: for knocking out the retaining ring and removing the hub.
- 🛑 Wheel wrench: a long lever for unscrewing wheel bolts and hub nuts.
☑️ List of required tools
⚠️ Attention: The hub nut is on Nissan X-Trail T32 tightens with enormous force (about 200 Nm). Without a powerful wrench or pneumatic tool, it is extremely difficult to unscrew it yourself.
If you are not confident in your abilities or do not have access to a professional puller, it is better to contact the service. Incorrect installation can cause the new bearing to fail after a few thousand kilometers, and you will lose money twice.
What to do if there is no puller?
If there is no special puller, you can carefully knock out the old bearing through the mandrel, but this is risky for the steering knuckle. A safer method is to remove the entire assembly and work on a bench with a press.
It is also important to prepare a place to store removed bolts and nuts so as not to lose small fittings. Place them in containers or tape them to the body in order of dismantling.
Stages of dismantling the old hub assembly
The process begins by removing the wheel and brake caliper. Remove the two caliper guide bolts using a 14mm socket. Be careful not to disconnect the brake hose unless instructed to do so. Just hang the caliper on a wire or hook so it doesn't hang on the hose and damage it.
The next step is to remove the brake disc. If it is stuck to the hub, use a hammer and spacer to gently knock it out. Sometimes you have to use a special puller, but in most cases sharp blows to the inside of the disk from the back side are enough.
Now you need to unscrew the hub nut. This is the most difficult stage. Use a wrench or impact wrench. After unscrewing the nut, remove the steering knuckle from the ball joints and steering joint. To do this, unscrew the fastening nuts and knock out the pins of the ball joints with a hammer, prying them off with a pry bar.
- 🔩 Unscrew the caliper mounting bolts and carefully hang it.
- 🔩 Remove the brake disc, clean the surface of the hub from rust.
- 🔩 Disconnect the ABS sensor if it is not integrated into the hub.
- Very simple
- Medium difficulty
- Very difficult, you need a special tool
- Didn't do it, just a theory
After the steering knuckle is removed, you can begin to press out the old bearing. To do this, use a press or puller. You need to press strictly in the center so as not to damage the seat in your fist. If the bearing is assembled with the hub, then the entire assembly is replaced.
⚠️ Attention: When removing the steering knuckle, keep an eye on the brake hose. Do not twist or pull it, as this may cause it to rupture and leak brake fluid.
Clean the seat in the steering knuckle from old grease and dirt. Use a wire brush and solvent. The surface must be smooth and clean for the new bearing to seat evenly and tightly.
Proper cleaning of the seat is the key to a long life for a new bearing. Any dirt or rust can cause misalignment and rapid wear.
Installation of a new bearing and assembly of the unit
Installing a new bearing requires precision. If you are replacing only the bearing, press it into the steering knuckle using a driver.
