just got some bellows of e-bay.

siteunseen, did you get those bellows you talked about? Are they the same ones I bought, or one of the other alternatives?

Here's some pics of the pinion gear bearings. There are two of them, and on the later racks like mine, they are identical. I've done a little digging and I believe the earlier racks used just one roller bearing at the top, and a sleeve bearing down inside the rack housing. But I've got two roller bearings. Here's the top bearing which is pressed onto the pinion gear shaft:

The bearings they used are intended to be side loaded, and because of the design, you can take them apart. Carefully pry off the grease seal, pop off the retaining ring, and the bearing falls apart. You don't HAVE to take it apart to clean it out, but you can do a more thorough job if you do. Here's the retaining ring popped out of it's groove:

Take the bearing apart, clean the old grease out, put it back together, and add new grease:

Here's the lower pinion bearing popped out of the housing. Note that this was not the easiest part of the job:

But after seeing the grease in there, I'm glad I went through the effort:

how did you manage to get the lower pinion bearing out?

how did you manage to get the lower pinion bearing out?

I used a device called a "blind bearing puller" which is an expanding mandrel on the end of a slide hammer.

You put the mandrel though the inner race of the bearing while it's down in the housing, expand it until it's tight, and then use the slide hammer to "knock" it up and out of the housing.

Prices for such a tool are all over the map depending on quality. Here's a pic of one such device. This one is a little over $50 on Amazon:

What is the main difference between the left and right inner tie rod? Measurements the same only the thread is different RH vs LH?

Outer tie rods the same except for RH vs LH threads as well?

Are they regular thread going onto the rack?

Both of the inner tie rods have right hand threads and can be assembled onto either end of the rack. And yes, the outer tie rod ends are the same except for the RH vs LH threads.

You could use all the same parts on both ends and just make up for it when doing an alignment. Not sure why they went through all the trouble to have the two sides different in the first place. Seems like a lot of extra expense for no "real" benefit.

The guy with the reverse thread taps and dies company also had the patent on tie rods?

Or he felt sorry for left handed people and wanted "neutral" steering. (groan)

thanks, only asking because one side is NLA. Both inner are the same on my '97 altima, was wondering why they couldn't be used the same way with z car inners as long as the outer tie rod went with the same inner.

Yeah, I've heard the same as well about one side being NLA.

I'm thinking that the guy who owned the left hand thread company had dirt on the suspension design guy at Nissan. :)

Grave diggin' here, but @Captain Obvious, do you know if the dirty boots shown below in the earlier post you made are the actual NOS ones with that wide separation near the outside two bellows?

I bought the car used so I cannot know for positive sure, but from the looks of the old boots that I took off, I would guess that they were  the ones that came on the car from the factory when new.
 
I don't remember if that apparent wider convolution spacing was as pronounced as it appears in the photo. It certainly didn't seem to be really needed for any "functional" reason.

I'm going to have to check the boots on 182. I think I noticed a couple of the end bellow sections being separated by a wide valley like in the ones shown above.

I currently have a set of boots on the steering rack that I THINK are the same as the ones you've put on yours- and I also have two sets of the non-useable moog ones with the over-sized inner bore. 

Eventually I'll need to get another set to go on 182, so I'm just gathering info at this point. Would be cool to get a set of NOS ones if they're in existence.

"Cool" yes, but "robust" maybe not. I'm a little skeptical about NOS rubber things. Most stuff NOS is great, but old rubber, even if new and stock, isn't always the best idea. Would be perfect for a trailer queen though!

I don't think I kept those old boots. I keep many old parts, even if worn out, but I think those boots hit the round file.

I must be more of a hoarder than CO, when I replaced my rack boots in 2005 I kept the old ones. I can't be certain that they were original but I purchased the car in 1978 and this was the first change.  The old boots don't have the "wide separation" but the new OEM parts I purchased do have it, the new part number is 48203-N3000, strangely my parts book says that pn was only used from 05/73 to 07/73.

Here is a picture of the new boot (48203-N3000) installed

And here is a picture of the old boot (was stored in packaging from the replacement boot)

nice. i'll take photos tonight of what i have at the shop for comparison. thanks dudes!

as for the N3000, i saw them available on a Z supplier website, and was wondering if I should order those. 

i believe the ones on 182 are similar to the ones you put back in the bag, CanTechZ...

 

I do the same thing lol. good for records, I guess

If you are in a pinch, the Renault Part 7701469657  fits perfectly and is as cheap as can be.

And these work good holding them in place, instead of the zip ties that come with them.
