I think your steering was OK to begin with before the "overhaul" But I also think that the knock you described is caused by two worn sway bar bushes. You should replace the two drop links while your at it. Whole job is only an hours labour and parts are quite cheap. Try Rock Auto.com they sell loads of them. This is my third Tucson. First one developed a knock at about 40,000. 2nd Tucson at about the same mileage and my current Tucson has 49,450 miles on the clock. Just replaced them and it rides ( and steers) perfect once again ( no noisy clunk every time I hit a pothole). You need to drop the subframe slightly at the footwell to get the clamps off.... My bet is, your guys lubricated the bushes with WD40 while they had easy access. Try it yourself .... spray the bushes and the noise goes for a short time..... If it helps.... I also think there is an airlock in the steering fluid. BTW: Hyundai tech guys know about this problem with the bushes not lasting that long. The rubber bulges out of the clamp under certain loading conditions. They fit a jubilee type clamp on the inside of the bushes now to stop it happening. but I think the rubber is too soft. When you take them off, the car is at a standstill and they don't look worn. They do however bulge out of the clamp slightly and allow the bar to move outside the design spec and this causes a knock. Sometimes you can even feel it through the pedals. Hope that helps. Mike
Hey Mike. Thanks for your words of wisdom. I'll certainly get them to check the Sway Bar bushes! As for the steering, there was definitely a problem as at standstill, there was a lot of play. That seems better now. You're talking about Subframe bushes as well, i was TOLD originally that the subframe bushes were worn and it was apparently a BIG job and that they had to lower/lift the engine out of the way first. :-0 Was worried about that! That was the dealer. I went to what i thought was a specialist in suspension and steering. They have never heard of subframe bushes... hahaha... well, i should have run away right then! They said they would flush the steering fluid in case there is "dirt" in there from when they worked on the steering. They'd better not charge me!!
Thanks again Mike!
Boy, drop the sub frame.. Need to give a little bit better info in your answer.
