With the wife and I planning a trip to Baja late next month, I've been hammering away at a list of things that have been on my mind... :sombrero:
I firmly believe that real tires make noise, but lately, mine were sounding more and more like a B52 a full power. Usually, that means a wheelbearing is on it's way out... I have been moving a brand new set of complete knuckles around for years, and recently robbed the calipers and brackets off them, so I decided to finish them off and use the wheelbearings so I can scrap the rest.
I couldn't feel any play in the old bearings, but the pass side one sounded perhaps a little dry when I rolled it over. I put the new ones on anyway, after pumping a bunch more grease into them through the ABS sensor hole. (Highly recommend doing this, as there's not much in there!!) I also retained the driver's side bearing as a spare, after pumping it full of grease too. The new bearings should last almost forever, since the originals made 220k miles, seemingly without issue.
Tires have needed a re-balance for a while now, so I decided it was a good time to bust out my tire groover and cut up the huge outer lugs to give them a bit more traction, and possibly less noise. I added alternating large and narrow grooves, hoping that it might reduce the tire noise some too. Front tires were feathered pretty bad, so some grooving should help the wear more evenly too.
(Should have taken a picture when I did it... Not as obvious what I did now that they're dirty...)
They balanced out better than before, and a subsequent trip to Denver revealed that it was the former pass side front tire that was making all the noise. (I moved it to the rear, where I could clearly hear it howling away...) The extra grooving reduced noise a bit right away, and after another 1500 miles or so, they've calmed down quite a bit more.
Finally, with it sitting on stands anyway, it was time to see what was up with the trans... It's been going to limp mode after a cold start, and getting worse for about three years now... Lately, even with temps only around freezing, I was occasionally having issues. I decided to do a fluid change with a pan drop to change the internal filter too, and check out the wiring. Last time I changed the fluid was when I did the trans cooler lines several years ago, and I put two gallons of Transynd in it. I couldn't find any Transynd locally this time, so I bought three gallons of Shell Spirax, which is also TES 295, and at least as expensive as Transynd!!
When I dropped the pan, the pan filter dropped with it...
I took it as a sign that the seal between the filter and valve body was shot, and probably allowing it to suck air when cold started, resulting in the faults I was getting, and subsequent limp mode.
The pan was completely clean, so the spin-on filter seems to be doing it's job. I checked the wiring, which was fine, and put it all back together with new pan and spin-on filters. Topped off with about 2-1/2 gallons of Spirax and it's been totally fine since, with no faulting out down to at least about 15F.
