it is a heck of an angle on that steering shaft,, I have replaced a boat load of those u-joints due to excessive wear... grease is great, but the stress on them is greater... jojo

so regarding phasing, those 2 u-joints at the box are not to be phased.. they are offset from birth.. It sounds like you have a good working knowledge of your truck, If the weld is suspicious, then maybe thats the issue. I believe you said you tried it on another truck and it worked fine.. one other thing? your box has a large yoke bolted to the top of the steering box, with a bearing in it. is it in the proper place? just curious? jojo

actually Bob, I do not know how far back the adjustable tapered king pins go, but if you look at your 'R' model, on the bottom of the king pin, you may see a 'cross' were the large cotter pin goes through... thats the adjuster. of course its only 90 degrees at a time, and not a fine adjustment. you may also have shims between the axle beam and the knuckle. if multiple adjustments are being done, I would be concerned about the thrust bearing at the bottom of the pin.. anyway, he probably has the newer style.. jojo

if you replace the top u-joint at the steering box, did you happen to flip the shaft yoke 180 degrees? and/or did you put the steering shaft in 90 degrees off? Thats all i can think of, if this is a steering issue and not a kingpin issue.. jojo

not the newer ones, i was stating that they are easy check and repair... jojo

My guess is the top cap on the king pin looks like a giant nut with 2 grease zerks? If so, just be sure its the king pins,, the style im talking about is actually a good set up, and I rarely ever replace them. they are not made the same way as Mack king pins. they are straight at the bottom like all others, but they have a roller bearing in the top and the pin is held 'UP' by a big nut under the top cap. they are easy to service if needed. I have, at times, taken the wheels off and pulled the top cap and bottom cap, (they just unscrew,) in order to inspect them for wear.. of course the simple way would be to jack it up and use a bar to lift up on the wheel.. jojo

I started to take pictures with my phone in recent years.. it has helped me a few times. but marking the lines is my go to approach. I used too prick punch the fittings and the valve, so when i have it off on the bench, i can swap/replace the fittings with ease.. jojo

thats a sweet looking truck. I would be proud to own that one.. i assume he said it was the last adjustment because it looked like there wasnt any more adjustment left? Just curious what he saw.. jojo

yep, treadle valve is bad,,, not to hard to change, just pay attention to the plumbing.. mabey get small colored zip ties to mark the lines and fittings.. you got this, Jojo

I think thickness would be the difference. I found that out on a 2 stroke Detroit last year, still an easy filter to get by using demensions if the part number is gone, jojo

I vote every presidential election. Unfortunately, this last one was discouraging, because there was a lot of ballot fraud that was exposed, Georgia and Michigan for example... and I still wonder how 81,000,000.. were able to vote, especially when we were told that 2 particular 'populations' in our country were not given the 'equal opportunity and access to voting booths and ballots'.?? I expect you 'TJC' to educate me... Jojo

This was back when the cam kit was complete, lifters, eup lifters, thrust washer, the 2 stupid studs for the A/C bracket, the book, i think a tube of Mack gray RTV, was there 12 EUP bolt's also? All in one box... maybe the RTV was handed out with each kit... Hell I forget.. jojo

I was re arranging my book cabinet when I found these, I new I had them, just not this many,, hell I know I gave many of these away over the years.. It was a trip down 'Camshaft' memory lane... jojo

so i guess he took the 2 u-joints apart at the steering box. one should have a cut out in the shaft so that the pinch bolt is put bac in the correct spot. the other has a groove all the way around for steering wheel aim.. those 2 u-joints are not to be phased, like a drive shaft. and really they cant be due to the cut out in the short shaft. and heck yeah, mark the parts before tear down. jojo

napa sells the filters... screw Mack dealer's... jojo

yes sir.. I have looked up service manuals recently, and for my Isuzu NPR. the 600 page book was 0ver $500.00. other books were over $1000.00 in 2 books,, anyway, I buy instant downloads, I got my Isuzu book for $40.00 put it on 2 cd's, and in my shop laptop.. I have a bunch of them, cummins, detroit, mack E-9 etc.. the Cat 3406 E book's (3 of them) are $100.00 ea. for the download... Cat always has to wave their d!ck.... anyway, cheap easy way to get the info... jojo

ok,, done laughing,, too funny... if the steering shaft was pulled out of the slip yoke, it may have been put back 90 degrees off.. is the shaft a 4 spline shaft? if so, it may be 1/4 turn off... if it goes 'easy-hard-easy-hard' good chance im right... been there done that, probably will again... jojo

I made some sticks with wooden dowels, and bought earth magnets and scuffed them the epoxied them to cut lenghts of dowels, then for extrac security, i put elec tape over them then around the tape to hold the overlapped tape. the magnets stayed glued, the tape is insurance that can be replaced with ease... $50.00 for all of it. $700.00 for lifter sticks on-line. of course these are not for E-6's, as you can easily hold the lifters through the right side. I miss the side covers... jojo

yeah, the company i have used, air arcs the bosses where the bar goes through after slicing the bar in 3 pieces, then he welds 2 clamp plates to the bottom of the boss,'s. it has holes drilled through for bolts, 7/8" i think.. the clamps when done, are at the bottom, but the trucks I had done did not drag them through anything, and they held up good.. I only saw them after 3 years before I moved on. so I dont know about now, 3 years later.. jojo

yes they do .. and even more on the heavier axles.. We used a hydraulic torque wrench. use a fork lift to hold the spring pack up-side down, and go for it.... I have used a torque multiplier a bunch of times..... Talk about ' row-row-row- your boat'... jojo

Amen Brother.. I will use PAI anytime.. Iv'e done 3 engines and had several tranny's done. they are all doing great.. jojo

hell, if you have mack build it, I bet $32,000.00 is going to be the final bill. jojo

you reckon the V.E.B.C. is failing or maybe a bad oring in it?? jojo
