noise might be coming from the silent blocks. if the car was up on the lift with wheels hanging in the air, suspension arms were lowered way down. how to cure this? jack up the car by putting a floor jack under the suspension arm, remove the wheel, loosen the nuts nolding silent blocks and re-tighten them. while you're at it, you might as well lubricate area where silent blocks sit on the shock tower (upper) and wherever you can on lower ones. use silicone based grease.

Guys, The sound was travelling as many suggested. The culprit was the idler. It looks easy to taker apart. Would I fill with axel grease? Is it smart to rebuild or best to buy new.

Some folks suggest filling it with automatic tranny fluid.
I filled mine with GL5 gear lube (same as what I use in my steering box) and it works perfectly, and the thicker lube does not leak rapidly.

Haha... I knew it I could by the sound..yeah gl5 will work... the Fiat service manual says to use 90wt. Ep

Rebuilt the old idler cleaning out the inside and filled it with GL5. It works now but still takes a lot to turn. I've read where some folks have drilled holes in the panels inside the idler so oil would move faster between compartments. Rather than alter the initial design i decided to go with an idler that has bearings in it. Ordered it from AutoRicambi and installed it last weekend. Works like a charm. Only thing was that the bolts from the old idler were not long enough to get good thread with the new idler. Quick fix with a couple 8.8 bolts that were longer.

With that said, is anyone interested in a good OEM idler. It works and does not leak. As i thought about it a bearing design makes more sence than the original for the idler.

Some people that installed idler with bearings claim that it makes steering lighter compared to OEM oil filled ones or those with rubber bushings.
Even when replacing a good working idler a bearing idler gives smoother and lighter feel when doing spot maneuver

have you experienced such an improvement ?
Or that "charm working" is similar to what a good OEM idler gives?
