Tilt Steering

Anyway to tighten up the slop at the top of a tilt steering column? 88 D150

This might help.

There are 4 screws at the base of the steering column that typically come loose. Disassembly of the steering column is necessary.

1st - Remove the steering wheel by loosening the nut under the horn button; then use a steering wheel puller to pull the steering wheel off of the splined hub.

2nd - Remove the steering wheel lock plate by using the lock plate puller tool to press the lock plate down; then remove the retaining ring.

3rd - Carefully remove the turn signal cancel cam; turn signal switch; key switch and plastic collar.

4th - Remove the steering column pivot pins. There is a special too for this job. (Some times you can see ths torx heads and get a long extension with a torx to tighten the bolts.That will keep you from having to pulll the pivot pins)

5th - You should now have access to the 4 loose bolts. They use an external torx head. Remove the bolts, one by one; apply threadlocker to the threads, then reinstall bolts.

This is the basic run down (from memory) of the job, there may be some additional (simple) steps. A good tech can knock one out in under 45 mins, however, if this is your first one; take your time and allow several hours for this job.
