chu613 Posted August 28, 2015 Share Posted August 28, 2015 I'm sure you're not the only one who has this kind of problems with the suspension. So they have figured that the bushings are not right and they've released new ones.It will take some time until they'll work things out with this suspension and until then guys like you will have to take the hit.It's sad and I can only imagine what I would have done in your place. Maybe you can work something out with the guys in Loyd if you really want to get rid of the truck.Like you said, this guys won't do it cause they know the truck.But trucks are so expensive now it's just ridiculous.

haulin-gas Posted August 30, 2015 Author Share Posted August 30, 2015 1800 km trip and no change in the handling problems. After 35 years of trucking this pile of junk is gonna put me under. Quote Link to comment Share on other sites More sharing options...
haulin-gas Posted October 21, 2015 Author Share Posted October 21, 2015 Well, after 22 months of fighting with the disaster known as Twin Y, it finally came to an end. After Mack invested an unbelievable amount of money and my time into this suspension, frame crossmembers and transmission,they gave up and agreed to get me out of it. Dropped off the truck at the dealership and am just waiting to take delivery of a new CHU with AL suspension and an Eaton 18 spd. I would rather have seen them take the truck back and write me a cheque for my 90 + days of downtime and the 4 sets of tires it went thru, but that will never happen.Hopefully the new truck will be reasonably trouble free. Hell, it couldn't be any worse, could it?If anyone out there is even remotely considering the Twin Y suspension, RUN AWAY AS FAST AS YOU CAN before you have to endure all the B.S. that I did.Thanks to everyone for your ideas and listening to my rants over the last year. 1 Quote Link to comment Share on other sites More sharing options...
41chevy Posted October 21, 2015 Share Posted October 21, 2015 Would have been nice to compensate you for the lost time and money but at least the finally did the right thing . . .way over due but at least they did it.

Hook n ladder 1 Posted October 28, 2015 Share Posted October 28, 2015 I had a similar symptom with my CH. Alignment was off abit. Tires wore to that "alignment". Got truck aligned and the truck seemed to "float" side to side until tires wore into correct alignment. The shop manager even said the truck would feel funny for a few weeks until the tires wore straight. Quote Link to comment Share on other sites More sharing options...
Mackpro Posted November 6, 2015 Share Posted November 6, 2015 Did the issue ever get resolved? I just hear from someone at Mack that the twin-Y ride rear suspension is to blame. Have you had the "trailing blades" replaced with the new ones that have the thick piece of plate steel riveted inside. I have done 4 so far here at our shop. The guy at Mack said the orignal trailing blades were to thin and flexed causing steering issues.Sorry I didnt read all the post's and now see you did get the issuse resolved. 1 Quote Link to comment Share on other sites More sharing options...

The guy at Mack said the orignal trailing blades were to thin and flexed causing steering issues.Sorry I didnt read all the post's and now see you did get the issuse resolved.It was in the shop for 11 days while they replaced the whole rear suspension. It started out as just a replacement of the pivot bushings, which had seized for the second time in less than 2 years, and ended up with new hangers, bushings and blades. Actually it made it worse because there was no "give" in the beefed up blades. Any type of ruts or uneven road surface and I had to engage the power divider or it would just start to spin.My new CHU has the AL suspension and I love it. I met the corporate sales manager with Mack Canada and he said he has instructed the dealers to avoid the Twin Y for western and northern Canada unless the customer plans on pulling no more than 80000 lbs and staying on cement highways.Mack still insists there's nothing wrong with the Twin Y, only the application that it's used in. According to them, mine was the only one that ever had issues so it's nice to hear there's been cases all over North America. Guess mine wasn't so "special" after all. 4 Quote Link to comment Share on other sites More sharing options...
Mackdaddy2030 Posted November 27, 2015 Share Posted November 27, 2015 Sorry to hear all you went through. I was told to stay away from the Twin Y also, thankfully I stayed away. Though I bought my '12 CHU used with 366,000 miles and it liked to wander around also. They replaced the drag link and it went away. What is the AL suspension? Idk what mine has, but it's not like my old '98 CH had with the Mack rears. This one has Eatons and the suspension says Mack. Quote Link to comment Share on other sites More sharing options...
Mackdaddy2030 Posted November 27, 2015 Share Posted November 27, 2015 I also liked the way my '98 steered. It was nice and effortless. The '12 is really hard. Quote Link to comment Share on other sites More sharing options...

Some are stamped Mack and some are Hendrickson. Quote Link to comment Share on other sites More sharing options...
