Idler arm..300SDL...

[Plantman]

How difficult is it to change the idler arm bushings on a 1987 300SDSL?

I realize the answer is relative to my mechanical experience, which is above average. I did body work for 5 years.

I just have never gotten into steering components.

I purchased Turbodiesels 300SDL(yes, the one with 300,000 miles) and I plan to pick it up Friday, weather permitting.

John claims it shakes a bit at higher speeds and that the idler arm needs to be replaced. I know their is a idler arm bushing replacement kit. Just need to know how difficult it may be.

Suggestions?

Thanks
