KAZU Posted September 26, 2007 Share Posted September 26, 2007 I found that u-joint of subaru and 240z can be assembled together. 1. Dismantle 240z u-joint by using hydraulic press. Be sure not to lose neelde roller in the bearing cups. 2. Dismantle subaru u-joint as above. This was from 1st gen FWD Imprezza wagon (18 spline). To drive out the cups, some spacers may be located between spider and cup. I put some welding rods. 3. I am not sure it is possible to disassemble without damage the oil seals. 4. Pack grease 240z cups and press them in. punch around cups. By the way, I ended up using EPS system from Suzuki mini car because there is no room for P/S pump.

Mike Mileski Posted September 27, 2007 Share Posted September 27, 2007 KAZU, you wrote: "By the way, I ended up using EPS system from Suzuki mini car because there is no room for P/S pump." Exactly what year and model Suzuki did you get your pump from? Mike Mileski Tucson, AZ Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 27, 2007 Share Posted September 27, 2007 By the way, I ended up using EPS system from Suzuki mini car because there is no room for P/S pump. I'm also interested in this. So this is the whole rack then? Motor on the rack itself? Any controller involved? Seems like there would have to be, otherwise you'd have severely light steering at speed. More details and pics please! Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted September 27, 2007 Share Posted September 27, 2007 So is the slop in the joint from a worn out cross piece or worn out bearings? Quote Link to comment Share on other sites More sharing options...
KAZU Posted September 28, 2007 Author Share Posted September 28, 2007 Suzuki EPS is column shaft assisted so it is not necessary to change stock 240z rack. This is essentially a smaller version of the EPS in BMW Z4. Bad news is that you can not find exactly identical to one I got because Kei cars are JDM only. To put it on 240z, column bracket should be cut as below. Also the columun shaft is 12-14" short to mate stock steering system. I fabricate new bracket because I want to put Tilton pedals at the same time. Tacho signal (ignition pulse) is needed to activate EPS and vehicle speed pulse is for deactivating at higher speed. The latter one might not needed bacause the assist torque is not so strong and my car will get higher caster angle (~10). If you want to keep stock ignition key and combination SWs, column should be modified. Suzuki column diameter is usually larger than 240Z's. I'll just convert all to Suzuki, including the wiper system. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 28, 2007 Share Posted September 28, 2007 Wow. That's cool, and even better that it all happens on the column instead of having to mess with the rack and a pump. That gives some real latitude to make it easy to fabricate mounts. Thanks for the info! Quote Link to comment Share on other sites More sharing options...
Careless Posted September 28, 2007 Share Posted September 28, 2007 these systems also have an artificial feedback/resistance feature that senses wheel-turn limit. As you ease off the turn-in, it will start to rewind, persay, so that it feels like a real pump driven steering mechanism that is pressurized.

Trevor Posted October 1, 2007 Share Posted October 1, 2007 Here's a simlar unit from a Jaguar.

78zlt1 Posted October 2, 2007 Share Posted October 2, 2007 I was told the Pontiac G6 has EPS , anyone seen that system? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted October 2, 2007 Share Posted October 2, 2007 The problem with the EPS is that it has a computer controller. The nice thing about the Suzuki setup is that it has the controller on board. I wonder how many of these things have a completely separate computer. I wouldn't go to the trouble of trying to install one that didn't have an integrated computer. Quote Link to comment Share on other sites More sharing options...
DrEaM Posted October 2, 2007 Share Posted October 2, 2007 i get the jist of whats going on here but i would have to see everything installed to get a better idea about how this all works Quote Link to comment Share on other sites More sharing options...
Careless Posted October 2, 2007 Share Posted October 2, 2007 i get the jist of whats going on here but i would have to see everything installed to get a better idea about how this all works In regards to the EPS systems: Whichever way you turn is assisted using a motor driven gear that turns the steering shaft for you, instead of using power steering pumps and hydraulic fluid.
