I replaced the u-joints on each end of the drive shaft today. The first part I got from Napa was incorrect, it was Precision 534G. The caps were too large to fit into the shaft and the yoke. The part that fit was a Precision 353. The existing u-joint had 353 on it too, but was aftermarket.

 

The problem is, it seems like there there is a lot of play between the joint body and the seals of the cup. Is this normal? Seems like too much slop to me, but I can't imagine the ears of the drive shaft have moved out by 1/2". The roads were icy tonight so I never made it past 40 mph to see if the vibration was gone.

 

2000 Sierra x-tra cab, 5.3, 4x4.

If the new one doesn't at least match the old one, then you have the wrong one. I'm not seeing a "353" listed

      Tonneau cover that does not leak water

      By parthery · Posted

      A properly installed tonneau will keep out 95% of the water.  As others have said, the only way to be completely dry is to either get a topper or an SUV.   I've run virtually all the trifolds and hard rolling that are out there.  My thoughts:   1.)  The leak points of any cover will be the front corners, and around the tailgate.   They will also leak if the rails are not installed properly.  If you take a electric/cordless ratchet and snug down the clamps, you run the risk of overtightening which causes the rails to sag.  When the rails sag it creates a gap between the rail and the bed cap and this lets water in.   2.)  Different manufacturers use different methods to try and seal the front.  The "driest" setup is probably the Leer HF650M, which uses double seals all the way around and doesn't require a foam seal across the front edge of the bed.  The Realtruck trifold covers (Bak, Undercover, Gator, etc...) all use a foam seal across the front, and drain tubes.   3.)  Realtruck has standardized the way that the cover attaches to the rail.  With the exception of the Extang Endure ALX, all other Realtruck covers use a plastic clamp which slides into a channel, hooks onto the edge of the rail, and tightens down. The "Realtruck Advantage" covers sold by GM dealers as an OEM accessory still use the "bolt through the panel" installation method.  Problem with these is over time, water gets past the rubber seal, into the panel, and once they become waterlogged they begin to delaminate (and weigh a ton.)   4.)  Unless you are using GM Rewards points, buy your cover separately.  Realtruck offers a 5 year warranty on BAK, Undercover and Extang covers.  Gators get either a 2 or 3 year warranty.  If you have an issue, they are much easier to deal with.  If you have an issue with an OEM GM cover, you have to go through the service department and GM Warranty processes to get it taken care of.   Recommendations based on my experience:   Hard folding:   1.)  Undercover Ultra/Armor Flex (identical except Ultra has carpet on the underside and a smooth finish.  Armor has no carpet but has a Line-X coating on the outside.) 2.)  Leer HF650M.  Has 4 panels instead of 3.  Double seals to keep the water out.  Downside is only a 3 year warranty and warranty only honored if you purchase from a Leer dealer.  If you have your dealer install it or buy off Amazon they won't warranty it. 3.)  Bak MX4.  They sell a ton of them.  A good cover for the money when you can find one on sale.  About to be redesigned to include a spring to ease opening and closing. (Supposed to be released 7/26.  Bak MX4 EZ-Lift)   Hard rolling:   Bak Revolver X4S or X4TS (has t-slot rails.)  Personal favorite and the one I use on my truck.  Easy to roll up one handed.  Doesn't block the rear window.  Only costs you about 6" of the bed when open as opposed to a retractable canister which eats up about a foot of bedspace.  Downside is it's either all the way open or all the way closed.   Good luck with you search.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Does any of this change if the seller dropped the price to $22.5k?  Mechanic is supposed to verify the transmission concern but they have not got back to me yet.  Even if a transmission needed to be purchased, I'm looking at <$30k which puts me right back to where I started.   In the meantime, I test drove 2 trucks locally back-to-back, one Denali and one SLE, the SLE was noisy, jerky, and did not inspire confidence, while the Denali was over $30k but just sold the other day.  If $32k buys you a Denali with 100k miles and this truck can be had for $32k with a brand new transmission, with GM parts warranty, does that skew things?   FWIW, all the trucks I drove locally had a much worse service history - emissions work, valve body work, one even had the whole transmission replaced with lower mileage than the one in TX.  I'm guessing those were "short trip" vehicles, as they only racked up around 100k miles in 6 years - a lot less than 164k miles in just under 6 years.

      Morality and Profit are two dogs fighting over the same bone. The bone looses.    Profit isn't always monetary. Position, power, leverage, prestige, celebrity, notoriety, fame; all forms of profit and those wanting whatever their currency is, don't care about who that pursuit hurts.

      Any 37 lin tire + wheels is adding a considerable ammt of unsprung weight, regardless of the height difference, so I stick to my mpg estimate.  Also, front and rear gear swaps are probably pushing $3k after labor.

      OCI, not when but why?

      By Grumpy Bear · Posted

      @KARNUT a few days (pages) ago I ask a specific question about the ISO 4406 test. The WHAT and WHY. I hadn't posted to this thread in awhile an yet the response had nothing to do with the CURRENT question, but continued the same rehash of "What we do" and 'What we've done".  It ignored the question in its entirety.    Now the CURRENT query is further being derailed. "I like what I've got and I don't want to talk about your question I want to talk about why I don't want to talk about your question".    Stan that isn't interesting. It's disruptive and unproductive.    I tired again further up this page with post on the same ISO method expanding that thought and this below     Irrational, it doesn't and it can't and it was explained not just by me but by the MANUFACTURE and was disregarded and Stan I find it tiresome. I get it when people are satisfied with there routines. I get it that some don't like having those routines questioned.   Know what I don't get?  That these people insist on making sure that no one else gets to explore something they DO find interesting and worth the pursuit.   Guy's if you don't like chocolate ice cream and chocolate ice cream is the topic why the compulsion to pick it up and disrupt the exchange of people that do?
