Steering rack questions

Postby Joose on Fri Oct 29, 2010 10:13 am

Hi all,

I wanted to ask your advice on two issues I have with my steering rack. Firstly, can someone help me identify this rack? The guy I bought the car from says it is an escort rack, but when I removed the plate to fill the rack with oil (as per Ford Escort Workshop Manual), I saw remnants of grease! Obviously I dont want to put oil in a rack that is designed for grease, and visa versa, so can anyone confirm if this is indeed an escort rack and that it takes oil:

The second issue is the angle of the steering arms. My uprights are from a Sierra XR6 (again, I bought it like that), and the steering knuckle sits further forward than it probably would for a normal Sierra upright. So, with the rack in position and bolted up, I end up with this:

as you can see, the angle of the steering rods is a bit.. funny. The steering arms are curving forwards, towards the front of the car. Is this going to be a problem? Can I leave it like this, or should I try to make the angle more straight?

thanks,
Gary

Thanks for the reply. Does the Golf rack take oil or grease?

You sure that it is a golf rack? Remember the MK1 has rear steer front uprights (i.e. steering arm sits at the back of the upright) while the cortina uprights are front steer. Fitting a rear steer rack onto front steer uprights will mean turning the steering left will turn the car right and vice versa.

Ideally you want the steering arms to be straight when the wheels are dead ahead. Having them at an angle will affect you steering geometry esp if you try and calculate your ackerman angle. However, looking the tyres this will be a road car (?) in which case the effect on the steering geometry would not bother me.

I wish I knew! With the rack connected up to the front of the uprights, the steering is not reversed, it is the right way round (left goes left), so does that mean its not a Golf rack?

I only have what the previous owner told me to go on. The reason I am doubtful is because of the filler hole. It is bone dry, and had some traces of grease in there. Now I know that some steering racks use grease and some use oil, although I cant see how to squeeze grease in through that tiny hole, so I am 90% sure its an escort rack and that it takes oil.

Joose, that rack look suspiciously just like one I got from Midas recently, labeled/part numbered as an Escort 2 rack.
And I belied it was one until my friend popped by and told me its not an Escort's. It did bothered me that the spline shaft sat at an awkward angle and the rack a bit long, so I went to see his car that has one and went back to Midas to get it sorted.
Turned out that the rack, although the part number is an Escorts, is actually from a mini taxi - Spectrum or something to that effect, listened with only half an ear when I am pissed. :twisted:

Perhaps that rack was also from that miss-numbered Escort racks from Midas? I got the correct one at the end of the day...

:( :( :(

I dont know why, but I have this sinking feeling telling me you are probably correct. The previous owner got a lot of bits from Midas, so its quite likely that this is also from them and the previous owner specifically mentioned it as a Escort 2 rack, so it would all add up. Its too late for me to take it back now though since he bought it more than 2 years ago, so I will just have to see how it drives and then change it if necessary. Does anyone have any idea what fluid I should be putting in this rack? I am 90% sure its oil, but I have never seen what a grease-filled rack looks like, so I could be wrong. Does the filler hole picture I posted suggest to anyone that it takes grease rather than oil?

Seems i may have the same Mini taxi rack ... grrr

I bought it from Brad, a long time ago and due to very slow progress on the car have only really noticed this after reading this post. Looks like I'll have to go shopping for another rack.. and will experiment cutting the current rack up into bits to see if its possible to shorten it, to get it 100% or as close as dammit to 0 bump steer. I raised and lowered my car the other day and the bump steer with the rack too wide is quite bad (even with a road car I would be weary)
