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

Sorry but I would need to do the testing myself, can you bring it over?

need a heavier clutch release bearing and flywheel probably i dont know how well you use a straight drive but riding the clutch always tears it and release bearing up alot faster

yes it sounds like the converter is no good,the converters purpose is, when you have a trailer it uses the brake and signal on the same bulb, so if you were to step on the brake and have the left signal on, then the left brake light would turn into the signal,on your truck it has sperate lights for signal and brake, the converter converts this into one light for the trailer, so just replace the converter and everything should work fine, hope this helps.

No a full series of test must be run to track this down. There is not simple fix.

Can you undo the engine mounts from the bottom and jack the engine up with a floor jack? Be careful you dont dent the oil sump; recommend you use a block of wood as a buffer between jack and sump. Unless it has proper jacking points. There may be better information in the repair manual: ' Hyundai Tucson Repair Manual 2004 2009 Service Repair Manuals
