Track rod and Steering rack question

Recommended Posts

Hi all,

I started in to what should have been a 20 minute job either side but in true Lotus tradition has become a bit more.

One of my track rod end rubber boots had perished and was broken open. I ordered a pair of new track rod ends and set about replacing both sides (I always prefer to do everything in pairs with brakes, steering and suspension)

One side took 20 minutes as expected but the other is not proving to be as easy. The track rod end has seized on to the track rod so I decided to take the track rod off the rack, not a big job and access is good with the right tools.

On the rack there is a lock nut that secures the track rod to the rack but there is a small key in both the lock nut and the track rod, when tightened in the right place they form a perfect hole over another hole in the rack itself, in these holes a pin/key/roll pin/grub screw is inserted to stop the lock nut or the track rod loosning. Unfortunatly some one had been there before me and mine was mangled so I couldn't tell what it was. After a few attemps at getting it out I eventually had to carefully drill it out. Everything has come apart easily now (and no damage to rack, lock nut or track rod) but as I've had to drill mine I've no idea what it was.

I've looked on my parts list and service manual but no mention is made if it. It looks a neat job (now the pin is removed) so I think it's standard but can any one tell me was it is and where I can get one. I don't see anything on the SJ site and haven't had time to phone just yet.

On the track rod end I added some heat and rust release spray and with the track rod secured in my vice have everything dismantled cleaned and ready for building up.

Any help gladly accepted.

Thanks

David

The rack is similar to an old Ford one, close to (thanks to a certain person who I was chatting to at the car safety check and evaluation day) a Ford Capri (Mk2?). The basic rack design is thus the same as most Ford ones of that era, including the Escort. So a refurb kit for a Mk2 Escort would probably contain the required components, even though the rack rate, total movement Rod Arms etc may be different.

I agree with Trevor. There are no holes in the rods on my rack (ohhh matron) and surely the adjustment needed in the track rods for alignment would mean that they wouldn't necessarily line up with the holes? Sounds like an 'aftermarket' modification.

This is standard practice for racks. What happens is that the cup that secures the track rod to the rack is tightened to a predetermined setting to preload the joint (which is why track rods should be stiff to move), then the lockring is tightened against the cup. Finally, a hole is drilled down the join of the cup and lockring and a pin tapped in to lock cup and locknut to the rack.

So it's not that the parts are supposed to line up: if you rebuild the rack properly the preload may change, putting the parts to a differnt alignment and necessitating a new hole to be drilled.

Some people (including those who should know better) weld the cup, ring and rack together...
