It's really not hard to replace inner tie rods. Can be done in less than 30 minutes (or less!). There is a lock washer, which is basically a washer with two tabs that are bent to prevent the inner tie rod from backing itself out. Take a long screw driver and bend those tabs out the way. It may be four tabbed on some. After replacing and tightening the inner tie rod in, bend those tabs back.
If you ever replace the inner tie rod again...

Inner tie rod tool. Basically, eliminates the use of a open-end wrench which sometimes you have no room for. May run up to $40, but it works with ease.
After you replace the inner and/or outer tie rods,
make sure you have an alignment done!
