Questions & Answers

I ordered these and they claim to fit my vehicle, but I have a 7. Not an eight, but a five. 7. according to the oil slinger shims (nine) Is it possible to use shims on the number seven?

Shim kit for Ford 8 "Super" carrier. GM 8" GM 12 bolt passenger car and truck, GM 8" GM 12 bolt passenger car and truck, GM 8" GM 12 bolt passenger 0", 8. 6", 8. IRS 6" and the year 1963 Corvette, model year 1979 Sorry, no number seven. There are five on the list.

Will the shims between the carrier and spider gears be replaced by this?

The pinion shaft, not the carrier, receives this crush sleeve eliminator kit. For the carrier, you'll need a completely different set of tools. And what you're referring to are thrust washers, which are a completely different animal.

Please tell me the id of the shims. I'm looking for shims with a diameter of 1 3/8" or 35 mm. ?

The spacer's identification number is 35. The shims are 33 mm in diameter and 2mm thick. 6mm ID

It was a success
5/5

Kit for shimming the carrier. For a gm 8, it worked well. My Hummer H3 has six seats. I couldn't find the quantity or thickness of the shims included anywhere online, so I used a cheap caliper to measure them and took a photo to aid others. For my carrier swap, I only needed two shims, but I'll keep the rest of the pack for future projects.

They appear to work fairly well
5/5

These have mixed reviews. br>They fit my 2013 F150 perfectly. br>I bought them to shim the differential carrier LEFT/RIGHT inside the pumpkin, as described in the product description. br>It appears that some of these were purchased for pinion bearing spacing and other purposes. br>There are two spacer packs included in this kit, each containing approximately 0. In each, there are 340 shims. Each spacer pack includes a 0. 25-inch left and right shim. 050 or 0. One of these, 075, has a lip that can hold a bunch of thin 0. 005 shims are a type of shim that is used in the construction of furniture br>Pick the Left shim, add a few thin spacers, and match it to the Right shim. Measure. Assemble a second shim pack for the carrier's opposite side. Place the differential in the mount. Take a look at it. When the original factory shims wouldn't fit after rebuilding the rear, it took me three tries to get the correct spacing. br>Measure the backlash of your ring and pinion. br>Purchase gear marking compound to double-check your pattern on the Ring and Pinion later.

While the product is useful, it is inconvenient to use because of three factors that could easily be addressed
3/5

br>The first is that they aren't laser marked, so you have to go back and forth measuring instead of simply looking to see if they are. Second, the shim combination was incorrect because everything you added resulted in even numbers, such as in my case. 004 is followed by a. 008 After that, I had two. The number 012 is followed by an asterisk (*). 020 I was in desperate need of something more akin to a. 003 or a are both acceptable options. 005 or . I was either too tight or too loose, so I ended up sanding one of the 011 to make better combinations of what you needed. 012 as well as the 0br> 008, on top of the extra test fits, is wasting even more time. br>Third, a few more shims would've been nice. I mean, how much would the extra shims have cost? I made mine work for 20 cents for a $30 product. br>Anyway, I made mine work, but I'll be looking for a different srt next time.

honestly
5/5

It appears that a crush sleeve is more difficult to use. With this set, I was able to get the correct preload, but a thousandth of an inch makes a big difference, so it's difficult to get it right. br> It took a lot of trial and error and seemed to take longer than using a crush sleeve, but I believe this is a better long-term solution. If you don't mind extra pinion test fits, I recommend doing this if your original gear set fails due to the crush sleeve crushing a little and damaging the pinion bearings over time. Keep in mind that you'll have to settle for a preload that's somewhere in the middle of the spec range rather than the one you had during the test fits. You can tighten it more, compressing the shims and metal even more to get it closer, but it's so sensitive that you'll end up somewhere in the middle of the range, but not necessarily at the same preload as your good pattern during test fits.

I have a 2005 TJ Unlimited with the Dana 44 rear end, which is the shims that go on the outside of the carrier bearings, so take the advertised fitment with a grain of salt
3/5

I double-checked Yukon's website to make sure these (SK 30214) were compatible with my vehicle, but when they arrived, they were the type that goes on the inside of the bearing against the carrier rather than the housing. For a variety of reasons, this was extremely inconvenient for me. 1 I had to search the forums for a long time before learning that the older behind bearing style shims could be used safely, 2 I needed to purchase additional bearings to grind down for use as setup bearings, and 3 there weren't enough shims to account for the total thickness of the stock shims, so I had to remove material from the thick stock outer shims and combine them with these inner shims just to get where I needed to be. br>br>For anyone else in my shoes, I'm not sure if the shims listed for the Dana 44 HD are compatible with the non HD axle in the TJs or not, but they "look" like the ones I needed, so Yukon should probably update their parts catalog.

This is ONE shim, not a shim kit as described
3/5

005 shim! Now, let me explain why I gave it three stars. "Wide range of shim thicknesses," according to the description. Six shims are shown in the photo. "Shim Kits from Yukon Gear and Axle ensure you have the correct shims to make the adjustments you need to your differential system," says the product description. I was hoping for a "kit" when I ordered this. ONE was sent to me. 005 shim! To make matters worse, I did not receive two-day shipping; instead, I received three-day shipping. That's one more day my Jeep sat in my driveway, blocking in my car while I waited for a shim that would only help partially. I'll have no choice but to make a double-thickness gasket to act as shims. In a nutshell, this isn't a "kit" of shims; instead, it's a single shim. 005 shim is an absurdly high price for a single shim.

Don't give up, the extra setup time is well worth it
4/5

It'll come to you eventually. These kits were recently used to rebuild two rearends. It's a pain in the neck to figure out which shims you'll need to achieve your desired inch pounds of preload. It takes some time and a lot of trial and error to get the right shim combinations for the pinion. But,. Once you get it right, it's very nice, and you'll never have to worry about crushing sleeves again, so it's well worth the extra time and effort.

Gear for the Yukon If another Jeeper needs to know, I received 12 shims in various thicknesses with this kit
5/5

113 - 116 - 120 - 121 - 124 - 127 - 130 - 133 x 2 - 137 - 139 - 142br>The internal diameter of all of these shims is 2. With a total length of 244 and a diameter of 2 inches, it's the perfect combination. 992br>br>I was concerned because I couldn't find the right information on the dimensions of these shims (Yukon doesn't specify much, which is unfortunate) and their locations (inside or outside the bearings), so I read various contradictory opinions in response to the questions posed. So I took the risk of ordering without knowing what I was getting, but when I received the Shim Kit I needed to restore the Dana 44 HD rear axle on my WJ 4, it was with great relief and great satisfaction. Since 2002, 7L has been available. br>From a Jeeper in France, a warm welcome to all.
