Stated content

  1. Communication summary

    旋回操作時のクランク音（Clunk）、part 2 ここで扱う状態は通知 00-02-35-003A に記載されており、リサーキュレーティングボール式ステアリングを備えた 1999- 2002 C/K pickup および utility モデルに適用される。 一部の顧客から、ステアリングホイールに感じられるフード下のクランク音について指摘があることがある。 この状態は、荒れた路面を低速で旋回するときに、より気づきやすいことがある。 TIP: この状態の症状は、2001年11月の TechLink の記事で説明したものと非常によく似ている。あの記事は、記事中に挙げた乗用車だけを対象としたものであった。 この状態への対処に必要な潤滑剤は、ステアリング系の別の箇所に塗布し、別の潤滑キット 26098419 を使う。 該当するトラックでは、インターミディエイトステアリングシャフトを車両から取り外し、スペーサークリップを取り外す。 次に、キットに付属のシリンジの中身を、完全に伸ばしたインターミディエイトシャフトの開口端に注入する。 開口部にプラグを差し込み、ウイングナットを締める。 シャフトのプラグをした側の端を硬い面に当て、シャフトを縮めてグリースを行き渡らせる。 正しく潤滑されていれば、シャフトのスプラインに 13 mm（1/2 インチ）のグリースが見えるはずである。 Machine translation (unreviewed)
