for the rack and pinion to work correctly it must be mounted to the axle?

and it will give you horrible Bumpsteer with a Solid axle?

Hi Parm,

If the Rack and Pinion Steering Unit is mounted on the axle (solid axle) how will you connect the steering rod/Pipe from the steering wheel?

Arka

Arka,

Sorry to answer the question you asked Parm and that too with a request for your thoughts.

I believe that it would possibly not be safe, though I have seen photographs on this forum of people doing it. The toe in and toe out will continously keep on changing with resulting tire wear and instability. How much I don't know.

For a sprung axle the Tie Rod keeps the Toe in and Toe out constant as the tie rod floats with the axle. I believe, the fixed axle requires a steering box with a drop arm turning one ackerman arm to steer one wheel and a Tie Rod to correspondingly steer the other wheel in keeping with the ackerman principle.

I believe, that the IFS is pnly compatible with a chassis mounted rack and pinion steering matched to the wishbone setup. Without going to the books, logic says that the Tie Rods on both sides should be under the point where the wishbone hinge to eliminate the mismatch in geometry.

Would love to know more for the experts.

nnn, since im going for Thar MDI, the PS just came as a thought, but im comfortable with the Thar MDI without PS.

since it would be a secondary vehicle for farm work and OTR only.

as Arka said, the MDI is still too basic in stock form and needs some upgrading for the OTR and otherwise.

my budget of 5L for the MDI could be extended to accomodate the upgrading, i would be happy even with it in its stock form as it serves my needs, atleast it would be factory build vehicle and not an ex army re build with frequent trips to my neighbourhood workshop for breakfasts!

Parm,

The Thar MDI should be brilliant in standard fit.

The Second hand ones will always be unreliable. Plus the effort and risk getting one readied is just not worth it. The reworked Ex-Army may end up costing the same as a new MDI.

I believe an MDI will be as good a drive as the Thar Crde for normal use, far cheaper to use (fuel consumption and repairs) and practical. I don't feel compelled to rush at 125 Kmph on the highways, which the Crde can achieve. The lower Fuel concumption of the MDI will be a great benefit with further expected increase in diesel prices.

Please may I request your feedback if you buy one. I may like to change our Gypsy with an MDI.

im sorry i should have mentioned the version.

im not worried about the AC or PS. i think the AC is doable, since the set up is similar to Bolero DI.

Arka, couldn't you use a splennex offset equalizer to align to the Pitman rib and use a jig to hold the two until the glue sets?

Yet to come across someone on the Board who got it done(AC) in Di! If Im not wrong, think read somewhere about AC in Di being a difficult job, maybe it was BD.

You can't register the DI in Bangalore because its BSIII. Guess quite a few at the dealership will tell you that it can be - but you legally can't - Unless you find someone who has an address outside of Bangalore city limits and register in his/her name.
