Refer to Workshop manual K:01:02 it is the bolt at the left side of the page where the trailing arm meets the frame. A better picture is in the Parts manual 5-3-0 fig #25 pn #106883. It is refered to as a trailing arm bolt in K:05:01 and :02. If you do not know that they were replaced order new upgraded ones from a Delorean vender. Count the # of spacers and replace exactly as removed or you will need an alignment. Loosen the bolt and rotate the head with a wrench, if the trailing arm moves up and down the bolt is bent and MUST be replaced. Be sure to torque to spec 55 FT/LBS WITH THE FULL WEIGHT OF THE CAR ON THE SUSPENSION. If the bolt is bent you may have to slice it up into little pieces to get it out. On an automatic car you will need to unbolt the rear carrier on the left to move the trailing arm to clear the trans.(Don't disconnect the rear caliper, there is enough freedom to move the trailing arm if you're careful.) --- In dmcnews@xxxx, "Jerry Harry" <jerryHarry@xxxx> wrote: > Can someone tell me what these are called in the parts book, page and number? > I find all kinds of things that I think would need inspection from time to time but none are called trailing arm bolts. > Thanks for the education. > Jerry > Vin# 4890
