i got this 99 sport xj...118xxx miles on it and got it @ 102k....changed oil every 3k after that and just did serpentine belt, spark plugs, tranny fluid, for the first time at 115k-116k...been noticing some issues...losing hp and tourque slowly and my steering wheel sqeaks and i have full pwr steer fluid...also it death wobbles slightly at 55-60mph...and at cruzin speeds (65-70) its got a noticable vibration i just wanna kno of any advice to render these wounds on my baby...any periodic maintenance i should keep up with than just oil and oil filter

this thing was knocking the other day...it stopped but it never made that noise before so i was worried bout it...(part to the right of compressor with green cap)

and heres my temp cruzin...

and my rpm's cruzin at 65

thanx for reading and love for responding...any advice for performance boost and precautions for anything breaking is greatly appreciated!

 

Squeak + speed wobble probably = ball joints, ask me, I'm an expert I just took two and a half days to replace ONE SIDE. Ok so really, if this is your problem I could help you out with a few pointers, there are better sources to be sure. Parts @ AZone upper and lowers both sides was about 140.

 

ball joints, the hubs old track bar bushings old control arm bushings lots of things cause DW, as for the temp 210 is normal

 

just fyi if it is ball joints

i have had bad luck with auto zone parts

if you have a napa or carquest around you, get their parts, it may be more expensive, but in my opinion, the are alot better, and last longer

just my two cents

 

do you have a lift on it?

 

I've never had a problem with Duralast stuff *Knock on wood!

I do love Carquest though! When no one else had a leaf pack centering pin, they did! They're the S***!!!

 

Don't really need photographic evidence of ya doing 65 mph, it is heard of that these trucks are capable of it. Now if it was something unrealistic like 80, I'd have to call you a liar.

But in all seriousness, don't worry about snapping a picture. And I would start simple, try having the tires balanced.

 

thanx for the advice all!...well have gotten tires balanced...didnt go away...its been this way for almost 2k miles now and i do remember les schwab saying somthing bout bottom bushings going out...and that was around 2k miles ago...so some pointers on that and ball joints would be great

 

That comment right there gave me a good chuckle! lmao

I got to 90-100 (don't really know but the needle was pointed straight down) on the freeway last weekend and that was with my lifted XJ!!

I've gotten to about 90 on the freeway with my '92 XJ and it's stock

For some reason the stock one feels scarier at that speed LOL

 

for lower bushings i'd save some $$ and just get a lift and replace everything with new better parts

 

that is not the AC compressor. it's the AC accumulator / receiver dryer. and the green thing is the EVAP service port. IIRC that noise is normal.

 

Your RPMs look fine for cruising at 65, no worries.

The wobble has nothing to do with your oil change, plug/wire change, belt change at all. Its most likely a wheel out of balance, or bushings/ball joins/etc going bad. Normal wear and tear.

As for the squeaking...is is really the steering wheel? My fiance's TJ makes a rubbing/squeaking noise when you turn the wheel, when parking and such. It could just be the material rubbing.

Now, if its actually suspension, it, too, could be bushings. Or shocks/springs that are wearing.

None of these things seem too terrible, just normal crap you must maintain as a vehicle owner.

I'm curious, though, how exactly do you know you are losing HP and TQ? Have you put her on a dyno lately, or is it just your mind messing with ya? I know mine does sometimes...

 

Your little vibration is not a big deal yet so don't get all excited you don't need advice on this or that. You need to find someone to take a look at it with you and shake the tires wile they are off the ground. Its not hard to tell were a little play is. Could be a ball joint or a tyerod could also be a crack in your frame. We can't tell from here. Find someone who knows more than you to take a look at it. If your in WI shoot me a pm.

 

i get readings on torque and hp from BIG O when i get my tires rotated

 

Might think twice before completely changing the tranny fluid at that mileage.
