How do I change tensioning roller? Help, I need this done ASAP

[2Fast996]

I have been hearing a noise which sounded like a bad bearing for the past week or so therefore, I removed the ribbed belt in hopes of finding the source. Upon turning the tensioning roller, I found it to be loose on its axis and making a grinding noise on spinning. All of the other items, ie. alternator, A/C compressor, etc. appear to be fine.

Am I correct to assume that the tension roller needs to be changed?

If so, how do I do this? Do I simply turn the 24mm bolt counter-clockwise to remove the mechanism or is there more to it?

How much should I expect to pay for this item at my local dealer? I'd rather have an idea before getting ripped off without fair warning ....

Sent you a PM, see if that is what you are looking for?

Sorry, can't answer your question as to whether you should change it. However, here's a diagram of how the roller attaches. To remove, you turn it counter-clockwise while countering on the bolt it is mounted on.

Good luck!

Hold the front of the pulley with a wrench and loosen the nut behind it. They are about $50 from dealer.

Thanks to everyone for your input and assistance. The pulley change was very simple especially with the graphics.
