Loose and leaky

[random_tox]

Our $250 racer is loose and leaky where the axle or CV joint or whatever it is exits the transmission. (Pictured) I'm guessing this is a bad bearing and is not easy to replace.

Any input?

[E T Haggis]

i have the same exact thing

[toy-driver]

Same here. My bearings are definitely shot. I've considered this to seal it up:

Axle seals

Dude,Your collection of succesive photos is great!!

My Autopower Cage mounts entirely within the pass compartment, does the bars going back to the rear struts compromise anything.

Where do you go to race.?

The picture with the snow is a crack up.

Good Luck,

mr2tim

ps are mr2's easy to find where your at/

^^^^
Thanks man,

The rear cage supports couldn't be done with a rear window, and would be tough fit without modifying the engine lid. Obviously the side covers have to be cut. Since our car is basically disposable, and seems a bit flexy, we figure it would be worth stiffening up the structure.

Mine and my brother's cars are both racing the 24 Hours Of Lemons (car = $500 or less excluding safety equipment) at Altamont in California in 2 weeks. My brother's has also raced at Thunder Hill.

MR2s are fairly rare here in Utah. I've had my eye out for a good daily driver MK1 for most of this year and have had no luck. My brother in Oregon has several to choose from on Craigslist any given day.

Oh yeah, check our blog.

Sorry to re-hash this thread, but instead of creating a new one i though i'd post here.

I've got this problem as well, (i have an 86 automatic), and want to know what this actually means to the car? IE is the tranny going to slowly disintegrate as the bearing rattles around in there?

Really i'm kind of looking for an excuse to need to swap in a new tranny (5 speed )

It isn't leaking though, just moving around in there a little, and i almost think i'm feeling the feedback of that movement every once and a while, but i can never be sure if it's the roads or just me!

Any help would be great guys, i just really haven't dealt with any transmission stuff yet, so i don't know much about what's wrong/what it's going to do if i leave it.

We ended up just living with it. We just needed it to survive the race which it did just fine. (Our rear passenger hub on the other hand...) It seems about the same and still doesn't leak much.

I'd just drive yours until you can't stand an automatic any more (today) or until it falls apart.

[ebouwman]

is there anything i can do to make it fall apart faster?

[toy-driver]

[QUOTE=ebouwman;434483]is there anything i can do to make it fall apart faster?

neutral drops, sand, sledge, cutting torch, .40 S&W.....

[ebouwman]

neutral drops, sand, sledge, cutting torch, .40 S&W.....



mmmmmmmmm.... neutral drops...

well when i eventually get a new tranny i'll do the most massive neutral drop ever and destroy the tranny Like 6000 rpm or something

[toy-driver]

What my buddy did to a auto sentra he had. Throw it in reverse, shift to neutral while going about 20-25 backwards, rev it up really good and slap in into drive. Some how the trans held together.

Wow

I do kinda thrash my tranny already, not really bad, but all the little things you shouldn't do like shift into drive while still rolling backwards, and mild neutral drops, say 2000 rpm.

In a previous Post by Ben, he said "Axle Seals".

Ben hit the bullseye with his cryptic post.

You have to undo the axle out of the wheel hub, then "drift" or in the real world 'hammer' the axle stub out of the differential. Drain tranny oil before removing axle from Diff.

Axle seals are quite inexpensive, but they are a lot of work to put in $15 dollars worth of parts.

[mr2tim]

The main part that begins to "wobble" is the differential case which has the side gears inside. As the differential bearings fail it apparently deterioates the upper and lower pinion gears and side gears as well, thus the output "wobble".

Also, bolted to the differential is the ring gear which will, in turn, also 'wobble" and affect the alignment of it's teeth from which oftens causes noticeable noises associated with humming, chattering etc.

As the ring gear "wobbles" more and more, its affects the output shaft which has all the 1-5th gears around it. As the output shafts absorbs these stresses
the major damage will occur.

(Putting new seals on the exterior case will stop fluid loss only.)

Therefore, if you have your tranny repaired the rebuider will most likely want another differential (undamaged), he will supply new bearings for this and you'll be on your way.

If you get reports that gears 1-5 are damaged you might consider purchase of another transmission as the labor costs go way up if the main gears have to have attention.

That's a quickie on how this tranaxle tranny dies.

I've got an auto though, so i WILL NOT rebuild it, just not worth it when i could do a manual swap.

I kinda figured as much about the seals, i was pretty sure a small piece of rubber wouldn't stop it from moving.

I was told by somebody that 1 - 3mm of play is acceptable, i think i'm within that, anyone else have a take on the "allowable" amount of play?

I'm going to talk to a trany shop tomorrow and see if they have any info, mainly i just don't want a spectacular transmission failure causing me to get stranded. From the sounds of it i'm safe from that though for now
