    Hello,
    when inspecting the suspension and chassis in the mazda I noticed a strange symptom.
    If I tear the element of the "hinge" behind the support of the right drive shaft (from the wheel side), I sense that there is radial clearance (about 3-5 mm).
    I didn't take a photo so I mark with red arrows on the photo found on the web:

    This does not look like a loose bearing, because the shaft going from the support to the crate does not move.
    Is there a spline there and may be loose on it?

    I don't hear any knocks (although the play is quite large).
    I jerked it, because from time to time at speeds of about 80-90km / h or when loading I feel the vibrations from the right.
    I have new discs and new tires, so something else vibrates.
    The question is now, if it were an internal joint, would I feel no looseness by pulling on the rollers on both sides of it and not like now, pulling on its housing, and the support point is the shaft from the chest side?
    I detect slack in place (arrow 1) by moving the joint housing towards up (arrow 2) and down (arrow 3)

    I wonder if replacing the articulation joint is enough, because since the splines in the articulation broke, it could also break out on the shaft.

    after what you describe, this wrist ends life. If there is slack there, during acceleration and 60-90 speed it will cause vibrations and if you release gas at this speed, the vibrations stop.

    Well, but in that case why the frame has this joint clearance in relation to the shaft rigidly coupled to this frame (on multi-line).

    In the drawing, the green shaft is the shaft coming out of the gearbox, supported just before entering the joint (into the housing).
    The blue shaft is the shaft that goes into the joint, the shaft runs to the outer right joint and then to the hub.

    If there was slack there must be a disconnected connection.
    Where is the length corrector for this fight depending on the angle of the wheel or swingarm? Inside the articulation or is it just where I have slack any spline?

    If that were the case, the shaft would have to slide in the bearing of the support. Is that so
    I mean to know what set of parts to stock up before taking it apart because it will take some time and I don't want to immobilize the car for a few days.
    I am worried that the whole joint moves relative to the shaft, so the shaft itself also needs to be replaced.

    Is there no one in this forum who has changed the driveshaft in a mazda and is able to comment on this?

    I got the same half shaft from Mazda today, but unfortunately it was also loose in the same place as mine (maybe slightly smaller but I didn't buy it in the end).

    solving this problem is simple and applies in every car with the same connection of the right polos with the support as in the car.
    grease the spline connection of the shaft coming out of the chest to the inner joint !!! over time, the grease from this connection somehow evaporates and then you can hear the crunching, wheezing and rattling when starting, adding light gas in gear 1.2. the looseness on the multi-body will not disappear because it is supposed to be so, but the grease muffles these small knocks, if this procedure does not give the effect you need to replace the inner joint and also lubricate it in the place of this connection POZDRO

    Hello, did I solve the problem with this slack? Is it really this place in this place should be? How to unfasten the drive shaft in this place to lubricate it?

    There is almost everything shown (hammer pounding is missing; P) step by step, unfortunately comment in English ..

    Place shown in the movie in 6min. 30sec. (06: 30/14: 07) is the last place where I would take to unfasten elements ..

    The massacre with this clatter, with diagnosis also ..
    Good luck!

Topic summary

The discussion revolves around the radial clearance observed in the right drive shaft support hinge of a Mazda 3 BK 2.0B 110KW. The user reports a 3-5 mm radial clearance and associated vibrations at speeds of 80-90 km/h, despite having new discs and tires. Responses indicate that the issue may stem from the inner joint, which can develop slack over time, leading to vibrations during acceleration and deceleration. Suggestions include inspecting the spline connection for wear, lubricating the joint, and potentially replacing the inner joint if lubrication does not resolve the issue. A video link is provided for visual guidance on disassembly and lubrication procedures.
