The reason for fitting the bolt downwards is a safety critical thing You don't want it dropping out as you drive along

I think every rally car I've ever seen has the bolt pointing upwards so that a bent tie-bar can be changed in a few minutes at a service point. I used to drill and split pin the bolt and use a castellated nut years ago, but nylocs are so effective now that I just use one of those, then distort the thread with a punch (lock-peening) and I've never had any problems. A bigger problem has been the nut at the front of the tie bar and I've seen a few of those ome loose when rallying in the forests. Again, a castellated nut and spilt pin is the correct way to prepare the car.

i fit the bolt downwards, which i can still do with everything in place, and use both a spring washer and a nylock nut, job done

i usually use both a nylock nut and springwasher when i undo a nut on the lil runt. like to see them come undone by themselves.

also you shouldnt reuse nylock nuts or spring washers

Peter,

I wasn't knocking what you do, just pointing out that engineering convention for that assembly is bolt downwards

If you look under most if not all modern cars you will see bolts going up hill that is the design route for that assembly etc......
