05 Yukon, 4.8L 4x4
When I bought the Yukon the 4WD was not being used due to there being an Axel seal leak in the front differential. Did a full rebuild on the front suspension/steering sans the pitman/idler arm as I did t have the help to test it properly, second set of hands, and didn’t have the parts available at the time.
I replaced the front Axel seal, easy job went smooth after having to get the correct seal a 3rd time, and did a full rebuild of the front end including :
Upper control arms
Lower control arms
Front hubs driver/passenger
Front sway bar link
Front sway bar bushings
Tie rod ends
Inner/outer tierods
Cv axels driver/passenger
Cleaned the front knuckles up
Cut/cleaned all threads and bolts
New struts.
So here’s why I’m running into, I’ve kind of asked around before but no one could really give me a direction.
I’m getting a throw left and right but it only occurs when 4WD is engaged.
When driving in 2wd I don’t have a throw and if it’s there it negligible I can’t feel it or decipher it through the terrible road conditions.
Now a little insight, I can’t really
Get a true alignment. There’s no alignment rack here and “driving to a alignment shop” isn’t an option. As there’s no road out…. So I did a tow alignment on it myself before rolling it out.
The only two things that I can’t think of is that either the camber/caster is so far off that it’s throwing it out of whack and when engaged in 4WD with power to the wheels it’s causing a throw that’s being able to be felt in and seen in the steering wheel.
OR
The pitman and or idler arm are bad and I’m getting throw when engaged in 4WD because I have power to the front wheels which in turn causing in loose feeling in the pitman/idler to be felt exponentially through the wheel.
I don’t I ordered the Quicktrick alignment system to be able to actually do an alignment just waiting for it to come in. I also have a pitman and idler arm ready but I need a second set of hands to help
Turn the wheel so the play can be checked.
What do you guys think? There’s nothing in the differential that I could think of that could be causing a literal throw like that, that wouldn’t just make the differential
Go boom. I mean they’re decent but they don’t that strong to sustain that much damage.
Hope someone chimes in on newbie and maybe helps point him in some other directions.
