  1. Communication summary

    低速旋回時のタイヤのこすれ音 一部の 1999-2005 フルサイズトラックおよびユーティリティの所有者が、低速旋回時（駐車場での取り回し）にタイヤのこすれ音を経験することがある。 リサーキュレーティングボール式ステアリングで、ステアリングダンパーを使っていないすべてのトラックおよびユーティリティでは、ステアリングロッド（センターリンク）を前後逆に取り付けることができてしまう。 アイドラーとピットマンの取り付け穴は、一方向にだけテーパーが付いている。 ステアリングロッドの正しい取り付けを判断するには、同種の車両と比べる。正しい取り付けでは、ステアリングロッドは、アイドラー／ピットマンの取り付け穴の外側、インナータイロッドの内側で、後方へ曲がっているはずである。 ステアリングロッドが誤って取り付けられていると、アイドラー／ピットマンの穴とインナータイロッドの間にあるロッドの曲がった部分が、車両の前方へ曲がる。 ステアリングロッド（センターリンク）を取り外し、正しく取り付け直す。 Machine translation (unreviewed)
