It doesīnt, using the car today I ran 80mph and the rev count was just over 2000.

The law gave me the once over..........checking my 4" cowl for legality.
It doesīnt show up in the paperwork, but they decided it was legal being made of metal not fiberglass.

They stopped me in town before I got to the freeway.
I need that big hicky to hide the illegal induction system under it.

It sounds like the Emission laws in Spain are as tough as places here in the United States. How does it work there?

I only have to pass a tailpipe sniffer.

They never saw the car before I took all the emissions stuff of it.
Even the engine swap passed them by.

Back to rear ends, this is funneee.

I have my bearings.
3.23 ring and pinion is on itīs way.
I have a bearing puller.
I have a pinion yoke wrench.
New yoke too.
Outer axle bearings....on their way.
I have an inch pound torque wrench.
A bunch of stuff is held up at Summit, waiting on the Yukon shims.
And a slide hammer is ordered.

Itīll probably be snowing when Iīm ready to go.....

I want the best of both worlds, acceleration and cruise economy..........
economy could, I suppose take the back seat....

Iīm planning a complete overhaul, ring/pinion, bearings and reusing my PowerTrax.
If I can get enough dough together, axles might be in there too.

This will be my first time "in the rear" so Iīve ordered a book and ībeen watching this,


My Summit cart floweth over.

I have an 84 Trans Am and run factory 215/65/15 tires (26" tall), factory 3.73 rear gears and a 700R4. I run 2600RPM at 70mph (115kph or so).

I like it because it's quick off the line and decent cruising. My car is carbed and I get 19 miles per gallon on the interstate, 14mph combined and around 12 if I stay in town.

The Yukon kits from Randy's and the Dewco kits from Tom's have the best shims, along with Timken bearings. Jim sells the Yukon kits.
I bought a richmond kit to replace my gears when I broke some teeth off and they whined terribly...sounded like the pinion gear was bad out of the box. The shop took them out and reinstalled them three times before giving up. Apparently the ring and pinion gears need to be "matched"..they couldn't ever get them to set right and get rid of the whine. So, I ordered a set of motive gears and poof...problems solved. I only get a little howl around 45mph. Sold my Richmond gears to a guy who was going to use them in a track car.

So far Iīve got the ring gear and carrier out, absolutely no preload on the pinion, itīll spin dead easy.
The gears are clean and undamaged.

I can assemble my new carrier and ring gear then install the bearings but Iīm still waiting on parts from Summit, no carrier shims until the 13th this month.

Iīve decided not to get the axle out, just too much hassle.
So Iīm on my back.....

I've been doing them on my back for 32 years. Keeps your abdominal muscles in shape. Just don't let anything fall on you. I had a Dana 60 differential fall out of a housing once and it almost got me in a very important place. Left a big chip in my concrete floor.

I undid the bearing cap bolts but left a few threads to catch the carrier as it came out.
Didīnt need to, it eased out nicely.

Iīm okay once Iīm under the car, just have to make sure all the tools I need are with me.

Yea, my 48 year old knees don't like getting up and down from the floor anymore. Probelm is now my 48 year old mind can't remember to get everything that I need before I get under the car. I always had plans to get a lift, but it never happened.

And I thought I have problems with memory at 62......err....63 !!

I already have a aluminum diff cover with bearing supports on it, Iīm also going to install studs for the bearing caps and ditching the crush sleeve for spacer/shims.
Upgrades recommended in a book I bought by Randy Lyman of Randyīs Ring & Pinion.
