During a routine service my dealership informed me that I need to replace the front shocks, idler arm bushings and upper control arms on my 86 300SDL w/340k miles. I easily replaced the shocks myself about 150k miles ago, so I'm thinking of replacing them again along with the other suggested parts myself (I've asked the PartShop for a price quote on the parts). It looks easy enough. Do you forsee any special tools/problems I might encounter? Best I can estimate, doing it myself should bring the job down from $900++ to around $500+. Thanks for a great site.
