I purchased my first Explorer, a 1993 XLT, that wouldn't start or run. It died on the old man I got it from running down the road. He was asking $250.00 for the truck. I felt like I was stealing it from him so I talked him into leaving the receiver hitch on it and gave him $450.00 for it. I had to, my concience wouldn't let me buy it so-o-o cheap. Diagnosis and findings were a split / cracked Flexplate that the spacer between the flexplate and the crankshaft became embedded in as the flexplate split.
Long story shorter - I went to a local wrecking yard after not being able to find a replacement flexplate at the parts stores with the aluminum piece attached to it and found the flexplate and spacer were two parts instead of one. The wrecking yard sold me the flexplate, spacer and BOLTS for $25.00 but since he carried the truck up front on his loader and removed it for me I threw him an extra $15.00 to make it an even $40.00 (this way he didn't need to make change).
I will try to find (remember) where I put the extra 6 flexplate bolts I have from the job and get you the information on them tomorrow exening. Both sets were identical in length, size and head size - for my 1993. I can't remember if the flexplate he removed for me was off of a 1992, 1993 or 1994 but it matched my old one (except for being two parts instead of one mangled mess).
I don't know if it will make a difference but again, if I remember correctly, my Explorer and the parts Explorer were both 4x4s. It has been a couple of months since I tackled and finaly finished that job (after owning the 1993 for almost a year and a half).
Finding the correct Transfer Case input shaft seal was another feat in itself. I had trouble finding the correct "flanged" seal. All of the parts stores wanted to sell me an unflanged seal and there was NO WAY I was going to buy an unflanged seal with no ridge to bottom it out on in the opening of the transfer case.
