any help at all would be great.

New ones are available here at Pelican Parts. Just soak them in WD-40, PB Blaster, or some other penetrating oil and let them sit overnight. Adding a little bit of heat always helps break things loose.

soaked them for 2 days mate...still didnt help..but thanks for the advice.

Heat them up with a torch, then try removing them again.

What happens if they are totally destroyed (rounded out)?

What would be recommended then? (almost ran into this myself)

Drill, heat, easy-out.

I'm putting this off, too. Actually, I dodged it when changing my transaxle seals by jacking up one side of the car high and filling the tranny through the flange hole while the flange was out. In my world, 6 CV bolts were easier than 1 fill plug!

Sears craftsman sells something called a Bolt-out. It removes stripped or rusted nuts/bolts. I have a set and it has been one of my best tools, everyone that has seen it, has gone out and got their own set with great results.PN 009-52062 My outdated cat. says $49 . Good luck. Brian

To reinforce what others have said: for intact bolts that are just stuck here's what I do...PB Blaster overnight for several nights in a row...then heat with a torch...then, if not a perfectly snug fit due to slight rounding or variances, cover your hex head with aluminum foil to fill any void...make sure its perfectly straight in and fully seated, dig any gunk out of the plug recess first if needed, and use a good breaker bar for well-controlled torque...repeat the process if no go...

I had a fill plug that was so badly rounded out that I had to weld a bolt with a 17 mm head into the plug, then use two pairs of vise grips on the shank of the bolt to remove the whole mess.

Please, please, please, tell your mechanic that it doesn't have to be that tight... just tight enough so that they don't vibrate out.

I feel your pain...My fill plug is completely rounded out and there's no way the 17mm is going to get it . At least the drain plug loosens easily. I have a new plug to put in, now it looks like I'm going to have to drill and use a bolt extractor. Is there going to be a problem with bits of metal going into the tranny?

[944 Ecology]

Its never a good thing to have bits of metal floating around in your transmission.

I had to use an impact gun on mine the first time I changed the fluid. The only way it would come out was air gun to 17mm hex, no extensions. I could only get the car so high in the air, and the breaker bar wasn't working.

I had a 924 4 speed transmission with a rounded out fill plug. I welded in an old 1/2 drive socket and out it came. I think the heat from the welding helped break it loose.

Hi! Why canīt we use the same thin Teflon tape as plumbers use in pipe connections? This tape must be able to withstand all temperature swings that can appear in our transaxles as well as in pipeing. I will try this in the next oil change.

I do, works great.

[drew1]

Teflon tape, teflon pipe thread sealer, or antisieze on putting new ones in.

The front wishbones are easy to replace, and the steel ones are cheap. Buy all new bushes and bottom ball joint whilst you are at it. Mark around the rear wishbone mount prior to removal to get a base setting for alignment when fitting on the new wishbone.

Geez, that was fun, that plug was really stuck. After I got the easy out started, I heated it up, then it took a wrench with a 2' breaker bar .
