Default Shifter rail slop, internal issue?

I have an 04 wrx, 5mt. Seems to have a lot of slop in shifter especially in 3rd. When in gear you can wiggle shifter around quite a bit. Already has kartboy shifter bushings, and tic upgraded u joint linkage. Crawled under car and the slop seems to be coming from the actual shift rail that goes into trans. Didnít know if there was a bushing in the transfer case or if itís just the rails inside the transmission wore out

It's possible to get some gating wear on the internal linkage, but what you're probably feeling is just the geometry of the cast metal piece attached to the shift arm inside the extension case. Subaru made a number of different variants on this part between markets and years (i.e. to cause the JDM shift knob to lean right in neutral, etc.).

Nothing worth disassembling the transmission for - you probably don't have an issue.

One thing that can happen but is rather unlikely is the fork itself has a pair of delrin pads that engage the shift ring - if one of the delrin pads falls out (very tough if the transmission is assembled), you'll get a little extra play.

Itís just really sloppy, 3rd and 4th seem the worst. When you push into gear you can wiggle shifter from side to side at least an inch. Replaced everything in linkage, I can see the slop in the shift rail that goes into trans when I lay under neath it.

The bushings on the part shown on my 05 wrx wagon had worn and were most at fault for the type of shift lever movement on mine.

Ive already replaced that on mine with the upgraded one from tic. The other end of that rod that goes into transmission is where i see the movement. Didnt know if there was a bushing in the case where it goes in or what. Need to look at a exploded diagram of a 5mt

There's no bushing in the case but there are bearings.

Just curious if I were to add the external spring (thatís on older 5mt) if it would help any. My lower bushing bracket already has the spot to hook it on

The Double roll pin that attaches the universal to the rail shaft was causing excessive play side to side. Replaced the universal and roll pin, when assembled used black RTV to take up the wear clearances, perfectly solid now.

Also look at the nylon ball socket at the shift lever. The plastics are old a brittle.

The ball and socket definitely wear out - replacing them with a bearing is a chore but it makes this a non-issue.

Are you talking about the ball and socket on the bottom of the shifter on the inside of car?

Yes - I had a nice write-up on how to change this for a bearing... but Photobucket pulled their BS either this year so this is all I've got left:
