Xiaomi’s electric scooters have proven to be reliable and technologically advanced, but even they can eventually develop a backlash in the steering column, a common problem that arises from vibrations when driving on rough roads or after a long period of active use. The staggering steering wheel not only creates discomfort, but also directly affects the safety of driving, so this defect cannot be ignored.
Owners of the M365, Pro, Pro 2 and 1S often face a situation where the front of the structure starts to walk from side to side. Fortunately, in most cases this does not require expensive repairs in the service center. You can do the lifting yourself, with a minimum set of tools and basic maintenance skills at hand.
In this article, we'll look at all the stages of diagnosis and adjustment, learn which screws to twist, how to lubricate the joints properly, and when bearing replacements will be required, and look at the nuances of different modifications so that you can return your electric scooter to its factory rigidity.
Diagnosis: Identify the source of the backlash
Before you grab the tools, you need to know exactly where the shifting parts are. The Luft steering wheel on a Xiaomi scooter can manifest itself in several knots, and the methods of eliminating them are radically different. If you start to twist the wrong screws, the problem will not disappear, and in the worst case, you can damage the thread or deform the mounting elements.
First of all, do a visual inspection and a simple check. Take the handles and try to swing them left-right, and also up-down. Notice where the steering pipe connects to the base of the deck (footrest) and the folding mechanism at the top. Often drivers confuse the back of the steering wheel with the beating of the wheel or the weakening of the bushing, which is a completely different malfunction.
⚠️ Warning: If you hear a characteristic knock inside the steering column (in the pipe) when swaying the steering wheel, this may indicate wear of the bearings or lack of lubrication, rather than weakening of the external screws.
For accurate diagnosis, follow the following steps:
- 🔍 Ask your assistant to hold the scooter deck firmly with your feet or hands while you try to stagger the steering wheel – this will help isolate movement.
- 🔍 Check the gap between the folding mechanism and the steering pipe: if the pipe goes inside the "glass", the problem is in the adjusting screws.
- 🔍 Check the place of attachment of the steering wheel to the deck: if the backlash is observed at the very base, the bolts of the lower mount may have weakened.
Once the source of the problem is identified, you can proceed to work place preparation, and make sure you have good lighting and sufficient manoeuvring space around the vehicle.
To perform the work on the elimination of backlash on electric scooters Xiaomi M365 and their modifications will require a specific, although inexpensive set of tools. Using inappropriate items such as pliers or universal keys "all in one", often leads to the slithering of the faces of the bolts, which will greatly complicate further repair.
The main tool for working with the steering column fasteners is a hexagon. Complete with most scooters comes the basic key, but for deep adjustment it is better to use a set of high-quality hexagonal keys or a rattle with the corresponding heads. You may also need a screwdriver if you have to remove decorative elements or a speed sensor.
Additionally, prepare a lubricant. Lithium lubricant is great for rubbing metal parts, and for rubber seals, it is better to choose a silicone spray so that you do not damage the material. Remember to clean the work area of dust and dirt so that abrasive particles do not get inside the mechanism when disassembling.
Adjustment of the folding steering gear
The most common reason for the rudder to stagger in Xiaomi models is the weakening of the screws on the folding mechanism (called the “hook” or “glass”). This is the unit that experiences maximum loads when driving and folding. If you notice that the steering wheel is dangling in the place of the fold, you need to adjust the fixing screws.
The folding mechanism has two main adjusting screws: one on top (often hidden under a rubber cap or plastic lining), and the second on the side or bottom, depending on the version of the scooter. To access the top screw, you may need to remove the decorative pad that is usually held on latches or glue-based.
The adjustment process is as follows:
- 🔧 Weaken the counternut (if any) or immediately start twisting the main adjusting screw with a hexagon.
- 🔧 Write the screw clockwise until the backlash disappears, but the folding mechanism still needs to work.
- 🔧 Check the rigidity of the fixation: the steering wheel should not turn or stagger, but the hook should snap with effort.
Screw nuances
If you twist the screw, the folding mechanism may stop closing until the end, and the lock will not enter the groove, in which case the screw needs to be twisted back a little, the ideal state is when the hook closes with a noticeable, but not excessive force, and in the closed state, the backlash is completely absent. It is important not to overtax the screws, as this can lead to deformation of the metal or cracks in the body of the mechanism, the adjustment of the gap should be made gradually, with constant verification of the result. Eliminating the backlash at the base of the steering column If the folding mechanism is tightened tightly and the steering wheel is still wobbling at the deck itself, the problem lies in the lower mount. M365 The steering tube is inserted into a glass welded to the deck and fixed with several bolts, and over time, the vibration weakens these connections, creating a dangerous backlash. To access the bottom bolts, you often need to flip the scooter or put it on the end. Be careful: in the inverted position there is a risk of damaging the screen or the gas/brake handles, so it is better to use a soft substrate. Find the bolts that press the steering pipe to the base. Their number can vary depending on the modification (usually 2 or 4 bolts in a circle). Tighten the bolts cross-to ensure that the pipe fits evenly. If after tightening all the bolts are backed, you may need a more screwed tube adjustments (ifer is used for the tube tubes). Verification of the result: 🛠️ Try to turn the steering wheel around its axis - it should stand dead. 🛠️ Swing the steering wheel back and forth - there should be no knocking. 🛠️ Ride a few meters, the extraneous sounds must disappear. The lubrication and maintenance of the bearings Sometimes the mechanical lifting of the screws does not give the desired effect, and the steering wheel continues to "luft" or creak. In this case, the cause may be dry lubrication or wear of bearings inside the steering column. Bearings ensure smooth steering, and their condition is critical for comfortable driving. Bearing maintenance may require partial disassembly of the unit. Remove the steering wheel along with the folding mechanism to access the top and bottom cups of bearings. Clean the old lubricant and dirt with solvent or Kalosha gasoline, then apply a new layer of quality lubrication. For scooter bearings Xiaomi well suited lithium lubricants with molybdenum disulfide. If after lubrication left, perhaps bearings have physical wear (working), in which case they need to be replaced with new. M365 They're usually 6,000 series, but it's better to measure them with a rod before you buy them. You need to be careful about installing new bearings, you need to put them through a box on the inner ring so that you don't damage the balls. ⚠️ Warning: Never use steering column bearings for lubrication WD-40 It's a solvent that flushes out the lubricant, which will cause the bearings to collapse rapidly. Table problems and solutions To make it easy to organize information, we've created a composite table that will help you quickly identify the problem and choose the method to solve it. Remember that timely maintenance extends the life of your vehicle. Symptoms Probable cause Method of solution Ridge wobbles in the place of the fold Weakened screws of the folding mechanism Lifting adjusting screws with hexagon Low Luft at the base (deck) Weakened bolts of mounting pipe Puffing bolts of the base, use of the thread fixer Low Script and Stiff turn Dryed lubrication in bearings Disassembly, cleaning and lubrication of bearings Average knock inside the column Bearing wear or lack of lubrication Bearing replacement or deep lubrication High steering wheel not fixed in folded form Tightened adjusting screw Weaken screw on 0.5-1 Use this table as a checklist for your diagnosis. If your situation is not described here or you are not confident in your abilities, you should contact a specialist. Frequently asked questions (FAQ) How often should you pull up the steering wheel on Xiaomi? M365? Checking the tightening of screws is recommended to be carried out every time 100-200 If you're driving on bad roads, you should check the mount more often. Can you drive with a little backrest? It's not recommended. Even the slightest backlash increases over time, which can lead to a breakdown of the folding mechanism on the go and a serious accident. Safety should be a priority. Which thread fixer is best to use? For scooters Xiaomi optimal medium thread fixer (blue Loctite) 243). A strong lock (red) should not be used, because the next repair will be extremely difficult to unscrew the bolts without heating? If the screw faces are torn, use a special extractor head, carefully drill the bolt or try to pinch the hat with pliers (if there are protrusions). In extreme cases, you will have to drill and cut new threads. Will screws from other scooters work? Many of the fasteners of the Xiaomi M365 are standardized, but it is better to use original spare parts or quality analogues, since the length and pitch of the thread can vary in different modifications (Pro, 1S, Esssential).
