Yog tias koj tau muab VAZ-2108 rear hub bearing, qhov ntev ntawm qhov tsis sib haum rau cov lus qhia, nws yog qhov zoo dua los tsis kam yuav qhov kev yuav khoom no. Tag nrho cov kev ntsuas saum toj no yog muab los ntawm GOST 520-2002. Txawv teb chaws analogues ntawm lub spare qhov chaw yog tsim nyob rau hauv raws li cov kev cai ntawm ISO 15: 1998 thiab muaj tib qhov ntev.

Yuav ua li cas to taub tias nws yog lub sij hawm hloov lub log bearing

Ib qho ua tsis tiav rear hub bearing VAZ-2108 tuaj yeem tshaj tawm nws qhov ua haujlwm tsis zoo:

  • pom tus yam ntxwv rumble ntawm sab ntawm lub log;
  • lub log tsis sib npaug;
  • rov qab tsim.

Pom tias lub rumble tau hnov los ntawm ib lossis ob lub log tsheb, maj mam kuaj xyuas lub log bearings. Koj tuaj yeem ua nws txoj cai hauv koj lub chaw nres tsheb. Tsuas yog rub lub log tsheb thiab tig nws los ntawm tes. Nws yuav tsum tig tau yooj yim thiab sib npaug yam tsis muaj suab nrov. Tom ntej no, tuav nws nrog ob txhais tes thiab sim co nws ntawm ib sab mus rau sab hauv kab rov tav. Yog hais tias lub log tig tsis sib xws, thiab thaum nws loosens, ua si yog xav, npaj kho.
