FTX Carnage Bearing Kit Fitment and Rebuild Checks

A rough FTX Carnage is rarely improved by adding more power first. If the wheels feel notchy, the drivetrain sounds gritty or the vehicle coasts poorly after a run, an FTX Carnage bearing kit is one of the most worthwhile maintenance purchases you can make. Fresh, correctly fitted bearings restore smooth rotation where it matters and remove a common source of heat, drag and premature wear.

The important part is fitment. Carnage platforms have existed in different versions and configurations, and a bearing kit must match the vehicle in front of you rather than simply the name printed on the bodyshell. Confirm the exact model and inspect any parts that have been changed during previous repairs before ordering.

Why bearings matter on an FTX Carnage

Bearings support the rotating parts throughout the vehicle: wheel hubs, gearbox shafts, differential assemblies, steering components and, depending on the setup, the motor and transmission. They work in dirty, high-load locations where water, dust, impacts and overtightened hardware can shorten their life.

A single seized wheel bearing can make a Carnage pull to one side, reduce run time and put extra strain on the motor and drivetrain. A worn bearing inside a gearbox can allow a shaft to move under load, which may damage gears or cause inconsistent mesh. These issues often begin quietly. By the time a bearing is visibly rusty or completely locked, the surrounding parts may already have suffered.

Replacing the full set during a rebuild gives the drivetrain a known baseline. It is particularly sensible after regular wet-weather running, a heavy bashing season, or when rebuilding a used vehicle with an uncertain service history. If only one bearing has failed and the rest are recent, replacing the individual size can be the more economical route. The right choice depends on the condition of the whole vehicle, not just the noisiest corner.

Choosing the correct FTX Carnage bearing kit

Start by identifying your Carnage version as accurately as possible. Check the chassis layout, gearbox housings, hub carriers and wheel arrangement rather than relying only on online photographs. A model name can cover variants with different hardware, and previous owners may have fitted optional parts, replacement hubs or upgraded transmission components.

A model-specific kit is the quickest option when the vehicle remains close to standard specification. It groups the required bearing sizes for a full rebuild and reduces the chance of overlooking bearings hidden inside the transmission. It is still good practice to compare the kit contents with the vehicle as you strip it down, especially if you know it has had repairs.

Shopping by measurement is the safer method for modified vehicles or for replacing one failed bearing. Read the dimensions from the existing bearing where possible, or measure the inner diameter, outer diameter and width with callipers. Measurements are normally expressed in millimetres in that order. Do not estimate by eye: a small difference in width or outside diameter can prevent correct seating and create play.

Bearings also need to suit how the Carnage is used. A vehicle that sees dry car-park bashing has different priorities from one routinely run through wet grass, loose soil and puddles. Quality rubber-sealed bearings are a practical choice for most RC use because they provide good contamination resistance while retaining smooth movement. Metal-shielded types can offer low drag in cleaner conditions, but their protection against water and fine grit is more limited.

Signs it is time for a rebuild

The quickest initial test is with the vehicle switched off and the wheels clear of the ground. Turn each wheel slowly and feel for roughness, tight spots or a dry clicking sensation. Hold the tyre at the top and bottom, then check for unwanted movement. Some play can come from hubs, hexes or suspension hardware, but a worn wheel bearing is a frequent cause.

Next, remove the wheels and inspect the hubs. Brown staining around a bearing, damaged seals, side-to-side wobble and a bearing that does not turn freely are clear warning signs. Do not assume a bearing is healthy just because it spins when unloaded. Under the force of a fast run or a hard landing, a pitted race can bind and accelerate wear.

Gearbox and differential bearings deserve the same attention. Gritty operation when rotating the centre drivetrain, a transmission that feels stiff after removing the motor load, or oil and dirt collecting around output shafts can justify opening the assembly. This takes more time than changing wheel bearings, but it is far cheaper than continuing to run a damaged bearing until gears or housings are affected.

Fitting an FTX Carnage bearing kit properly

Set aside a clean work area before stripping the vehicle. Keep screws grouped by assembly and take a few reference photographs as you go. The Carnage is straightforward to work on, but photos can save time when routing wiring, refitting suspension hardware or closing a gearbox.

Remove old bearings carefully. Press them out squarely using a suitable driver, socket or bearing tool that contacts the outer race when working in a hub or housing. Avoid levering against plastic edges and avoid striking the centre race to force a bearing into or out of a component. A damaged bearing seat can leave even a new bearing loose.

Clean the bearing pockets before installation. Mud, rust flakes and hardened grease stop bearings sitting fully home. Check the surrounding plastic and metal parts for cracks, ovalled holes and burrs. If a bearing is loose in its seat, replacement bearings alone will not cure the problem. The worn hub, carrier or gearbox case may need attention too.

When installing a new bearing, press only on the race that is being supported. For example, press on the outer race when fitting a bearing into a hub. Pressing through the inner race transfers force through the balls and can mark the bearing before its first run. The bearing should sit square and fully flush without excessive force. If it will not go in easily, stop and check the size, orientation and cleanliness of the bore.

Before reassembly, rotate each shaft by hand. The drivetrain should feel free but not loose. Do not overtighten wheel nuts, suspension screws or gearbox fasteners in an attempt to remove every trace of movement. Overtightening can pinch bearings, distort plastic components and introduce the very drag you are trying to remove.

Avoid the common bearing mistakes

Packing bearings with heavy grease is not a cure for wear. Excess grease can create drag and collect abrasive dirt around exposed areas. Likewise, spraying oil into a seized bearing may make it feel better briefly, but it will not repair corrosion or pitting inside the races. For a dependable rebuild, replace rough bearings rather than trying to revive them indefinitely.

It is also worth resisting the temptation to replace only the easiest bearings every time. Wheel bearings are accessible, so they are often changed while the gearbox bearings are left for another day. If the vehicle has been run in water or has a noisy transmission, inspect the less visible locations as well. A complete kit offers value because it lets you service the vehicle systematically rather than waiting for each bearing to fail in turn.

After the first short run, check wheel rotation again and look for unusual heat around hubs and the transmission. A bearing that becomes hot quickly may be incorrectly seated, overtightened, contaminated during fitting or installed in a worn component. Correcting that early protects the new parts and helps the Carnage stay consistent when it is driven hard.

For exact-fit replacement bearings, 888-RC makes it easier to shop by FTX model or by the dimensions taken from your existing parts. A careful check before ordering and a clean installation afterwards will do more for reliable running than any shortcut.
