UAZ "Patriot" pivot: description and replacement

In the front axle of cars produced in Ulyanovsk (in particular, on the Patriot) there are pivot knots and joints of equal angular speeds, which ensure the transmission of torque to the wheels in any position. To make the node work properly, you need to know how to maintain and change the pivot. UAZ "Patriot" (see the photo of the node in the article) is also equipped with them. So, let's look at what this element is for and how to replace it correctly.

Characteristic

What is the pivot? UAZ "Patriot" is equipped with this mechanism from the plant. The pivot is a rod with a swivel joint of a pivot and a ball bearing. The element is located in the front of the car. The pivot provides the ability to control the wheels without breaking the torque feed.

Functions

This mechanism acts as an axis around which a swivel fist swings. Also, the pivot is a connecting component, which integrates the ball and rotary cam into a single unit. The pivot provides the necessary rigidity and perceives the moments of forces from the pivot.

Varieties

There are several types of these mechanisms:

• Factory pin UAZ "Patriot". The device of the element assumes the presence of plastic inserts with a spherical support. The manufacturer produces lightweight components that require adjustment of the gaps. Replacement of pivots on the UAZ "Patriot" with their own hands is made as wear liners. The cost of factory elements is from 5 to 8 thousand rubles per set. The resource is up to 50 thousand kilometers.
• Reinforced. This is the pivot of UAZ "Patriot" of a new model. It is completed with bronze liners. Often used by amateurs off-road. The mechanism is issued in the form of a repair kit. Who makes such a pivot? UAZ "Patriot" can be completed with elements from the companies "Sollers", "Vaksoil" and "Autohydraulics". The mechanism is marked "for particularly heavy loads". Unlike factory plastic, bronze - more hardy pin. UAZ "Patriot" with such an element perfectly withstands impact and rotary loads. Reviews say that the element has a resource of 100 thousand kilometers. Thus it is necessary to make lubrication every 20 thousand. Reinforced pivots can be purchased for 8,5 thousand rubles (price per set).
• Bearing. It is a good analogue factory. The UAZ "Patriot" pivot on bearings does not require constant adjustment and has a long service life. The cost of such a mechanism is 2 thousand rubles per unit.

What to choose?

Choosing this or that type of spare part, it is necessary to remember that each species is suitable for different operating conditions. For example, if you drive primarily around the city, you need to buy a bearing pivot. UAZ "Patriot", equipped with such a mechanism (with plastic inserts), is managed very easily. If you often drive in the absence of roads, use elements with bronze liners. However, note that the first 2 thousand kilometers the steering wheel will be very tight. At the end of this period, the mechanism will finally work and be ready for full operation. Bearing pivots have averaged characteristics on asphalt and dirt road. Reviews are advised to purchase products from Altai company "Vaksoil". She offers kingpins with a castor angle of +8. This greatly facilitates the management of the car.

Why does it fail?

This mechanism fails due to the destruction of the rim of the cups, which closes the ball. At some point, this part simply splits. As soon as the detail loses its shape and strength, there is a backlash. Determine the failure can be by the characteristic knock and the creaking of the mechanism in the front of the car. Also the part fails due to the natural fatigue of the metal.

How to replace? Instruments

To replace the pivot in UAZ Patriot car, you will need the following tools:

• Set of heads with ratchet.
• Set of car keys.
• Lubricating syringe with solidol or lithol.
• A hammer.
• The puller.
• A set of new pivots.

An important point is that the mechanism changes in pairs, even if the neighboring element is in good order.

Instructions

So, how to replace this mechanism yourself? Initially, the car is installed on a pit or a lift. Next, you need to hang out the front wheel with a bad pivot. Then you need to get to the bipod of the steering rod. Nuts must be unscrewed with a "24" key. Also the lube bolt of the pin is removed. On cars UAZ "Patriot" it is located in the middle (between bolts of steering draft). Now we need to remove the top cover of the kingpin. To extrude it, you need to use a puller. Screw the tool bolt into the lubricating hole. Next, the puller nut will move down the thread path, thereby pulling the kingpin cover up. So we extract it from the body of the fist. The lower part of the element is pressed in the same way. Next, remove the ball and carefully clean the swivel fist from dirt and dust. We install a new pivot knot. An important point - before installation, the mechanism must be treated with plenty of grease. This is "Litol-24", or solidol. Then the bottom cover is in place. It is fastened on bolts of a joint of steering draft. The latter is also fastened to the seat, and its nuts are tightened, tightly pressing the lid into the housing. Then the top cover is installed. She will not sit in the corps to the fullest. Therefore, you need to knock it gently with a hammer. Next, the pivot knot "syringes" through a specially retracted hole. Then a screw plug is screwed into it. After installing the bipod of the steering rod, the wheel is installed in place. The car is removed from the jack. A similar operation is performed with the neighboring pivot mechanism of UAZ Patriot car.

Additional recommendations

When replacing this mechanism, try to avoid skewing the top cover when installing it. To do this, it is better to draw it into the body with 4 bolts, and twist them crosswise. However, even with the correct installation technology, there will still be a small gap near the cover. If water gets there, the node will quickly fail. Therefore, it is so important to ensure tightness of the connection. To do this, install several rubber gaskets. They can be made independently, from a bicycle or car camera. During operation, the element "gets used" and the need for gaskets disappears - after 500 kilometers we check the gap, remove the rubber elements and completely tighten the bolts. The cover must fit tightly, without gaps.

Why can not you immediately tighten a new part? It's very simple - it can split. Therefore, we wait until the part is fully used, using the same gaskets. Another point - if you are installing reinforced pivots with bronze liners, do not forget to adjust them after a thousand kilometers. Break-in should be carried out in a gentle mode. If properly installed, the element will serve about a hundred thousand kilometers.

Conclusion

So, we found out what the pivots are and how to replace them on the UAZ "Patriot" car. As you can see, you can do it yourself. However, this requires a special puller. Do not forget about the gaps (we seal them with gaskets), which will subsequently be worked on.
