thomastractorsvc Posted October 11, 2016 Share Posted October 11, 2016 I popped the hood on the 85 Superliner yesterday and the dust cover boot that keeps the grease in and dirt out on the lower half of the steering shaft is torn up. I wiped the boot off enough to get some electrical tape around it and so I could run it today. Meanwhile I called Mack they had to make "phone calls" to the HQs to get advice since the boot is NLA. After several hours of waiting for my call back a gentleman called and said they had a boot that might fit but they were not sure and it was a 2 day out order and $50 and they had no idea if it would work. This is the part number off the quote 25160249, I dont think it is a Mack number as the guy stated something about spicer. The picture was from last spring but you can see the accordion boot on the lower half of the steering shaft. Any help would be appreciated. Quote Robert"I reject your reality and substitute my own."

41chevy Posted October 11, 2016 Share Posted October 11, 2016 If you can't locate one, you can try a 4x4 shop for a shock absorber boot for off road by Rancho or a similar company.

kscarbel2 Posted October 11, 2016 Share Posted October 11, 2016 Spicer was the vendor of your steering shaft (Mack vendor code 2104 in the days of the former Mack Trucks and its superior parts system). Your Mack dealer should be easily able to view your steering shaft assembly's breakdown and see the 2104- number for the boot, and then supercede it to the latest number (if it indeed has a part number supercession). From what you're saying, Volvo has superceded it to NLA (No Longer Available). You could ask your Mack dealer for the original Spicer boot number, and then call Spicer at 1-800-621-8084 and inquire about the difference between that number and the 25160249, i.e. inner diameter at the ends where it mounts, working length expanded and compressed.

thomastractorsvc Posted October 11, 2016 Author Share Posted October 11, 2016 I was looking on summit web site but the diameters are odd sized. The upper is 1.75"/ lower is about the same with over all compressed is about 8", the ones I am finding are like 1.75" on one end and 2.25" on the other. I guess I can always tighten the crap out of it. Quote Robert"I reject your reality and substitute my own." Link to comment Share on other sites More sharing options...

thomastractorsvc Posted October 14, 2016 Author Share Posted October 14, 2016 I found a boot at the parts store cost about $7. I installed it today and it is okay, but I had to remove a ring spacer on the upper shaft . It took about 15 minutes to replace. I ch a need out the grade 8 bolt that was on the upper steering joint. When I disassembled the shafts, I noticed it was stretched. It was a grade 8 3/8" fine bolt. 1 Quote Robert"I reject your reality and substitute my own."

j hancock Posted October 14, 2016 Share Posted October 14, 2016 The price is right. What was the intended oem application for the boot? Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
thomastractorsvc Posted October 17, 2016 Author Share Posted October 17, 2016 It was for a Hyundai Santa Fe. The part was made in the USA. Have to keep an eye on it. The only thing I didn't like about it is on one end it has two horizontal sits that help to pull it on. When I sinched it down, it puckered two small holes less than an 16th of an inch. I don't run the front under water so I am sure it will be fine. 1 Quote Robert"I reject your reality and substitute my own." Link to comment Share on other sites More sharing options...
