Coupling rod function

The coupling rod is a spare part which belongs to the wheelbase of a vehicle. It is referred to in the garages also as a pendulum support or stabilizer bar.This part connects the stabilizer on the front axle with the lower axle support and transfers the forces between the two wheels during the deflect and rebound of a vehicle.The stabilizer itself is an inconspicuous car part yet, however, very crucial for comfort and safety.It connects not only the two wheels of each axle with each other, but also the wheels with the structure of the body. Its mission is to prevent uneven compression and to minimize the risk of tipping. Each vehicle has this construction on the front, some even on the rear axle. Among the well-known manufacturers are MAPCO, SWAG, VAICO, YAMATO and FEBI BILSTEIN.

If the coupling rod is defective

Connection is exactly between the actual stabilizer and the wishbone, for this reason, the pendulum supports flanges and the eyelet rubber-metal bearing or rubber bearings are used to protect it.The connecting rod is one of the parts subject to wear and should be checked at intervals of at least 200,000 kilometres. If there is a defect in the part, this manifests itself in loud noises when turning the steering wheel. When driving over bumps, potholes and poor road surfaces you'll sometimes hear a creaking or cracking in the wheel bearing.A defective tie rod should be changed quickly so that road safety is not compromised.The car is exposed to a higher risk of tipping and ride comfort suffers considerably.

How to change the coupling rod

If the connecting rod has been knocked out, you must know exactly which stabilizer must be replaced.Each vehicle has two different versions, one is 23 millimeters, the other 27 mm thick. In the 23 mm version, the stabilizer bar is simply pushed out of the stabilizer, the 27 mm version is then screwed in.The cost is almost the same in both versions, dismantling of the wheels will make the job quicker. The coupling rod is a nondescript spare part, but correct installation is essential for road safety. Everything you need can be found in our online shop particularly inexpensively. You'll also find many other spare parts in OEM quality for many car makes and models.
