My bakkie's steering rod was replaced with Graaf Brakes and when I drove my bakkie out there something was wrong. The bakkie was swinging over the road. I went back and after being told that I talk **** by the owner, said that the steering box needs replacement. Quote of R9200. FYI-Tyremart checked the bakkie and found nothing wrong with the steering box.] I got a second opinion at MTB service and repair who found that the steering rod wasn't fastened at the right hand side causing the swing of the bakkie. I paid R250 to do that. This morning I went to the owner of GRAAFF BRAKES to inform him of what was found and claimed that he must pay the R250. He started swearing at me, very bad words, and chaced me away. I could have had an accident due to his bad work.
