engine mounts replacemnt on 2005 Hyundai Elantra

Hi i have a 2005 elantra, 2litre diesel cdx and both engine mounts need replacing, is this a difficult job to do?? as im trying to save costs, its expensive at the main dealers, i understand they are hydraulic related,does this increase the difficulty when replacing like for like?? is it worth taking the risk to try and do it myself or swallow the cost of high dealer services, any info would be greatly appreciated, thanks.

I see beck/arnley has your mounts available Napa and Autozone both carry beck parts around $80 to $100 and the labor is .3 to .7 hours per mount. Get a estimate from another repair shop.
