2004 TL thumping noise on the front passenger end

It is hard to tell, without checking it. Iti could be the universal joint or CV, whatever you have, show it to a mechanic.

that noise is 1 of your belts. there is 3 belts on it. and with the power steering noise I think it is your power steering belt needs to replaced or agjusted

no you prob. need a window switch

i would 1st check out the front tires to make sure that they are not defective, if tires check out ok, then i would put the jeep on a rack at a garage, and check out all of the front end components, including c. v. joints and the wheel bearings.

MDX runs as FWD most all the time so I would have them check CV joints and boots usually need attention after 100K miles

Some cars actually require higher octane, if the manufacturer suggest higher octane for maximum effenciency your best advised to do so.

Have battery tested..if original battery then definitly replace

What you describe is consistant with a lifter not pumping up except at a little higher rpm, which would make sense. You have overhead cams, with hydrolic lifters. They pump up with oil. If you have one that is not fully "pumped", it will make a clicking noise when the camlobe moves it and it strikes the valve. This is not the only thing it could be...and maybe it is the tensioner, but if it is coming from the valve area....Also, your dealer should have a special stethescope so the mechanic can listen in spots, and move the pick-up to where the noise gets louder and make a better diagnosis.

Found it!!! Yay! I have a 2005, but this works for 2004-2007! http://www.acurapartswarehouse.com/body/b__5410-2005-acura-tl-4dr-base-navigation-ka5at-rear-door-locks-outer-handle.html Part # 22. Only $20 (with shipping) ~Sarah

You may not need the entire strut, just the part that serves as a shock absorber. The term strut refers to a complete assemby with coil spring and a central shock absorber. When their seals fail completely, whether gas or fluid filled,they are just a piston in a cylinder with nothing to damp their travel so they can slam at both ends.
American made 'shocks' were once only really effective for ~20k miles but both foreign and domestic have improved a great deal but one of yours may have left the factory less than perfect.
Shop the parts before you let the car go to anyone to see if they are scalping you or only marking their cost up a little.
