1998 SOHC, shudders when I accelerate.

[1998Explodasport]

I figured I would post this just to see if anyone is having or had similar symptoms. I have a 98 Explorer Sport SOHC with about 160k. All up to date on all maintenance; new plugs and wires, mobil 1 oil changes regularly, and did a filter and gasket kit and complete flush on the transmission with Merc 5. I actually just replaced the transmission filter and added new fluid again just to make sure I had the filter seated properly. Upon hard acceleration it shudders pretty bad. I didn't notice it until I replaced all Four tires, not sure if it matters but I did go up one size bigger than what it came stock with.

Does the shudder get worse as you accelerate? If so, that could mean an off balanced tire. I see you live in ma. Also check to make sure you dont have any ice build in your rims. That can throw a tires balance off causing a bad shake.

The shudder goes away as the speed increases at about 20-30mph, it goes away.

Sounds like your tranny is slipping.

Universal joint on the drive shaft is probably causing it.

The tires that came with it were 255 and I replaced them with the 265's and I soon noticed the problem. Anyone know of a fix for this besides going back to 255, I really like the new tires.

I still think it's your tranny slipping. Bigger tires would make it harder on the tranny, making the vibration more noticable. I had the same shudder feeling not long before my tranny completely died. Have you tried adjusting the bands?

When I first fealt the shudder I thought it was my tranny too. I guess at this point I wait and see if it dies. I have actually put about 15k on it since I first fealt the shudder. How do you adjust the bands?

I just bought a "98 xlt, an it "shudders" or hesitates in all gears, (except 1st) but only during light acceleration. I don't think it's the tranny. It seems more like a fuel or HO2 problem....Any suggetions?

:exp:The shuddering stopped when i when back to 255 Tires on my 98 Ex 4x4 Ed AWD,of course i had just replaced all tie rods and upper and lower ball joints,also,did a complete four wheel alignment and wheel balance.
