99 Impreza Outback Sport, 5 Speed, 237K miles..
I developed a slight 'knocking' in the front end when hitting bumps. Also developed a 'wheel shimmy' about the same time. Newer tires and I'm sure alignment and balancing are correct.
I first thought it was probably front struts. I got underneath (both wheels) and cannot find any play in the ball joints or outer tie rod ends although rubber covers look rough on the tie rod ends. Leaning towards tie rods as I noticed the 'knock' when going going over a very slight bump in the road the other day. Bump shouldn't have been enough to put much strain, if any, on the struts. Also would seem to be likely culprit for the wheel shimmy???
Just finished watching a YouTube video on tie rod replacement and realized that this could very well be a INNER tie rod issue???? Put car in the air and check for play in the wheel???
I fully realize that with the amount of miles on this car, it's probably time to replace them all and that will probably happen part by part in time but would like some thoughts on the most likely culprit now.
