Are drag links the same as top ball joints?

well says it all really! Found some that look the same but refered to as drag links.

Top ball joints are Transit drag link ends - *not* track rod ends as the book states. They should have an M18 fine thread.

Remember you need two from the same side of the van (can't remember which side it is) because one side is RH thread and the other is LH and (obviously) the normal way you would buy them would be one for each side of the van.

Bugger! They are left and right oh well, http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=21654&item=2416794677&rd=1

Bugger as well I asked for Transit track rod ends as per book, both right hand thread. They look OK but could they be the wrong part. Quinton Hazell Part no QD1117RHT (Equivalent MD1117R).

I would be gratefull for any help.

Regards.

John.

The thread on the track rod ends is slightly larger. No problem if you're making your own wishbones but if you go for bought ones most suppliers go by the 'M18 fine' specified in the book which is the drag link end.

What I don't get is how bit's of info' in the book (which appear to stick out in the way they're so deliberately put in) are wrong.

I mean yes, ok, a cutting list with metric/imperial/Whitworth/BSA/whatever conversions I can understand having inaccuracies** but the trackrod part number paragraph and the chassis build paragraph where it talks about the 'G' rails being specific for the Xflow stick out like a sore thumb and then turn out to be wrong.
Do these seem like 'accidents' to anyone else?


Cheers,

James


** Although why the hell the same errors are in Book2 without an amendment sheet I do wonder!

Guess that says it all too... ('scuse my ignorance).

I thought a track rod was the bit that goes back and forward between the steering rack and the knuckle.

So what's a drag link?

Before the days of rack and pinion steering, most vehicles used a "steering box". This was usualy based on a worm and wheel arrangement, or sometimes a recirculating ball mechanism. The box has an arm on the output shaft that is connected to the steering arm on one of the uprights via the drag link. A second link (the tie rod) connected the first upright to the one of the opposite side.

Sorry if this is even more confusing, it's hard to describe. Virtualy all the big offroad trucks in the US still use this system

Thanks, a temporary brain fade made me forget all about steering box systems.
